When I had similar problem with my camry, was the kick starter

his, is a crank no start situation, yours is a no crank no start situation. mkay?

I will never choose graphics over gameplay, never, look at RE5 it was cool, gameplay was cool also, RE 4 was very cool too, but look at RE6, graphics is way better than the the two previous ones, but the gameplay is total junk, I played and played before it became a big chore, then I decided to delete that crap, another game is RYSe son of Rome, graphics was like reality, but the game is just a fecked up rubbish.
I still feel like playing GTA same again whenever I hear any of the old school hip hop songs playing on the radio. so for me gameplay comes first, story, music then graphics.

scan the car first.

I just state it

I explained it in the conversation between me an Xavier, the post is up above

Specialist900:
does this mean the AC gas when filled last more than 10yrs before refill?

Yes, the MINIMUM is 3yrs.

pacino26:
Thanks bro.

Don't forget to ask him if he is comfortable with working with the high pressure side, and if he has a vacuum pump.

xavier0327:
Well first.. Twas working fine when I bought the car... Stopped working a month later, thought it was gas issue so I filled the gas... It worked for a coupla days then it started blowing hot air! I ve changed the compressor twice, filled the gas four times all in this year alone.... Now the mechanic says it electrical issue. I tire!!

once you filled it with gas, you got cold air for some days before it went hot, okay. There is a leakage somewhere in the ac circuit, the gas goes out from that hole,
Okay, buy a UV torch ( the type used to detect counterfeit money), buy a small bottle of UV dye and pour it into the compressor, just as you do to add oil, then fill it again with, the gas and drive the car till it blows hot again, then park the car in a dark place or at night, use the UV light on the entire circuit, any where you see a bright greenish glow when you shine the UV light is the source of the leakage.

what this video please

Also, refrigerant cans (r134a ) with UV dye or tracer are available, just look for it, maybe they sell it in your locality.

pacino26:
I'll personally marry the grandmother of that technician that will be able to fix the ac of all three cars, QX4 02' MDX 04' and VW Passat 99'

It's as if the cars are cursed since they lay their hands on them. The annoying part is they will always tell you the other guy wasted your money and like a child in a babalawo's house you'll believe you've arrived solution ground.

Enugu is my location.

They blow hot air. Though I've refilled and changed pressure hose to the condenser and the compressor. The rear vent on the acura blows hotter. It's either the dryer is leaking or this or that. After repair I'll have one week to enjoy the money spent then straight to the Sahara

The pressure hose, is it the metal pipe that goes from the compressor to the condenser?
If after filling the system with freon, and it works only a week, then there is a leakage some where, and its large, because the system supposed to be loosing not more than one gram a year, so if it looses more than 400 to 700g a week, then it is leaking somewhere. Does the kazeem have a vacuum pump? I really doubt it, look for somebody that has a vacuum pump and is not afraid to connect the red quick connect of the gauge to the high pressure side also, because it shows that he knows what he is doing.

Readonee35L:
The thing is ac issues are fixable in Nigeria . But most won't last.

Some mechanics are real clowns and they've ruined lot's of good vehicles,
*From changing ac compressor of a 2010 accord to knocking the engine,
*Frying the Ecu(brainbox) of a 2013 Maxima by putting the batery terminals in the wrong way
*From plug change to smoky engine
*Putting diesel in petrol engine
*Converting 2008 passat to 5s-fe
e.t.c

Let's talk about AC

Once a car's ac system has been worked on by our technicians i don't even think it will ever function properly again..
Unlike the old Fixed Displacement Compressor, the Variable Displacement Compressor (VDC) automatically varies its pumping capacity to meet air-conditioning demands. When the car’s cabin temperature is high, it increases its refrigeration capacity until the desired temperature is reached. Once the desired temperature is reached it automatically reduces its capacity to maintain the desired temperature.
With a VDC(auto compressor) there is no jerking of the engine brought about by the switching on and off of the compressor clutch as in FDC(manual compressor). In fact, some VDCs have no clutch at all. This results to a very smooth operation and improvement in fuel consumption.

Most recent cars come with climate control system but once they get faulty our techies can't seem to diagnose it and fix it properly , i don't know if they are scared of it, Their only solution is to recommend the manual compressor.
Recent Cars in Nigeria have been kazeemized and they have manual compressor installed.
Most of the technicians overcharge or undercharge the system or even use wrong refrigerant in charging it.

Effects of Changing to a manual compressor:
*More load on your engine
*High fuel consumption
*Rough idling
*Increased rate on engine wear.


My 2003 pilot has been to so many ac technicians since 2014 till date but between 3months the ac is back to the same issue, It won't get cold in hot weather, i now start to feel the car is cursed, Changed Compressor's condensers e.t.c. A techie worked on it recently let's see how it goes
I don't really drive the car much anymore.

My Venza also takes like 20-30 seconds to start blowing cool air in the hot weather, but it cools well it just takes time, tho the ac system was recently checked and it's working perfectly now and am looking at how it goes , the guy gave me a year warranty lol, One mad man was telling me to buy a manual compressor telling me it's the best but i frowned .

I've seen lot's of Benz with Peugeot compressor lol
Honda,KIA,Toyota e.t.c using all sorts of compressor and they end up rough idling and shaking like a grinding machine.lol

Many people buy car's with money but they don't even care to understand how it works, Thinking the mechanic will do all the work, don't be surprised if you know more than the mechanic.

auto compressor

Yes the is the truth
It is called magnetic clutch compressor not manual compressor, even it can be controlled by a computer.

xavier0327:
True talk!! Have been trying unsuccessfully to repair my Benz c240 since January!!!! Haba! Spent so much money and have recently decided to roll with the heat!

what is the problem?

princemillla:
OK now, do we av a pro in this ac fixing.

Had similar experience on my last mercury villager 1993 model. Spent close to 100k fixing the ac. It got a stage, the ladipo guys upon sighting me, would run away and I was giving discount at the park.

Now I av another 1999 model of the same car, is there anyone here good enough to handle it for me.

The whole system is OK working but compressor got hooked.

If you can kindly quote me

what is the problem.

earthrealm:
am not in lagos........for a tampered unit like urs...relying on the ac tech to fix it..is a waste of time.
you need to understand thoroughly what is bad n what needs to be done...then u can direct him..n even at that,,there is a limit to how much they would listen or agree with u..

like putting a guage on the hiside, they will never agree.....n its even risky if they grudlingly agree, cos they might hook it up wrong and injure somebody/themselves!!

2ndly...i doubt the guy has a vaccum pump, ..any serious ac guy that has n uses/understands the importance of a vaccum pump wud know his onions ..n wud hv resolved ur car issues long ago.
wud suggest u search for gauzz, he is in lagos....n can help u..
there is also another guy...who overcame his ac issues tru diy and research...he bought a vaccum pump n manifold guages in the process...search for him...i think his id is adaany10 or something,
i commented in his post, so u can get to his thread tru my profile

Guy you wicked oo, what you said is the TRUTH, The problem is if he can get somebody that has access to a vacuum (BTW it is spelled VACUUM) pump and go to YouTube. com and search for a channel called RATCHETS AND WRENCHES, he will learn EVERYTHING he needs to know.

prince088:
Thanks. Never knew AC could be this troublesome. With this wicked sun

how is it going?

prince088:
Thanks, i didn't plan doing this all mysef. The plan is to read this and be telling the AC tech guy to do all this. Sure they will have all the gauges. I don't av a vacuum pump, i will go check another AC guy now for all this. And yeah, the fan is the first thing to check even before condenser. Maybe they can do the flushing as u said. Will ask. I can't even remember if the fan motto was actually changed or worked on. Have checked the guy who fixed it to ask, he is not around. I couldn't even go to Ladipo again. Where is anyone of u located if i can bring it over.

Well, I would have loved to, but, I am not even in Nigeria, I live in Gabon

earthrealm:
i think you shud take things 1 step at a time.
1. get the original fan for ur car...n crosscheck that the duty cycle port hasnr been damaged..or the ecm side feeding the port--- a pal had the same situation, where the mechanic bypassed the dutycycle ish, n hard wired the fan to be blowing 24/7

2. you cant do ac work without a pair of guagaes.....go n buy one, costs about 3k to 5k depending on quality.
3. the only way u can escape not having a complete hiside n loside guage is to evacuate the system, vacuum with a vaccum pump until the pressure holds at -29hg , then get a sensitive scale max 2kg, place ur small 1kg bttle of gas on it...n refill ur system with the factory spec...wch u guys said is 500g
rememebr to add a lil oil say 5ml to 10ml..u can use a syringe to measure this.

the big question is..do u hv a vaccum pump?

about the unbalanced heat in ur condenser...till u replace with oem fan...we cant really b sure what is wrong, u may even hv a partially blocked condenser!
so to avoid spending money on unnecessary parts{condenser}, we need to work n think smart

I have hammered on this several times, but he has the car and is convinced that the condenser is part of the problem, so leave him to change it, one thing I am damn sure is that fan, except he will do it to run as far as engine is on, then he must change it.

steveyen:
The manual states; 5w-30 for all temp. 10w-30 or 10w-40 for ambient temp that will be above 0 degress. And it recommend mineral oil.

But I have been reading reviews for high mileage cars should use higher viscosoity oil. Though there re some engine oil specifically designed for high mileage cars but I doubt if that will be in Nigeria

those people are not wiser than the engineers that built the car.

prince088:
U asked about my friend's fan? That was what i explained.
Guess we missed each other.

There is no loose wire on the fan. My bro just took it out. Wheb he comes will check if how if i can get how many wires exactly.

My condenser is also very hot on the inlet and coller on the outlet. But the general surface, feeling it with my palms and using termometer, the left side is very warm to feel, but when i move my palm to the other parts, its cooler, thermometer even takes readings there as 36degrees.

okay you mean the out let is a lot, lot cooler than inlet, okay, yes the condenser has issues. poor circulation of refrigerant, you got to get another one.

Remember, the condenser cannot get rid of heat on its own when the environment is hot, so it needs the fan to do that, so if that of your friend works, it is because everything is in other, so even if you spend money on the condenser, it won't get rid of heat without the help of the fan, so for now concentrate your time on that fan.

prince088:
Yes. 2 cells. Both fan kicks in and out every now and then. Note the car was not so warm when i checked. As i just kicked it this morning and turned on the AC. I checked when the fan first shut down. The normal inlet is very hot. The pipe but cooler on the outlet.
Its the general surface of the condenser i'm talking about now

Why I am saying this is because, the fan is not cooling your condenser, so test it again and again, how many wires are connected to your cooling fan?

prince088:
@ cocoduck, earthrealm and others.
Found the first issue, i don't think the condenser is ok.
The left side is hot, even my themrmoter screams hi, when i move towards the right side, its colder there. Reads even as low as 36 degrees. Sometimes lower. Feeling the condenser with my palm on the left side is warm on the hard, but moving my palm towards the other side is normal temp, not warm at all. I tried same technique on someone's pilot whose AC is working perfectly, the whole condenser reads almost same readings 42 degrees, and everywhere feels abit warm. Unlike nine, where a part is much hotter.

Okay then, get another condenser, but don't forget that your friend's AC fan is working with full power while yours is not. The original fan, how many wires, I mean all the wires that was on the connector, how many were they?

steveyen:
It has been there since after I changed the oil last time that was couple of months ago.

It also comes with hard starting.

Besides the guy is suggesting changing to synthentic oil. I have had the car on Mobil XHP 20w-50 since.

your car has an owner's manual, right? Use it to find out the RECOMENDED oil for you car, that's all I can tell you. And you should be changing the oil as at when due, according to your car's owner's manual.

prince088:
Lol. I plan 1am tmr. Hope i don't sleep early. I have unlimited 1am to 7am. Semi thanks to spectranet. They are still cheats.

Hopfully this will let me know what to tell the tech. Cos in Naija, everything is trial and error.

Somehow i feel its either the condeser or the fan. Or even both. Cos if water makes it work in day time, and it cools to a fault at night. Then there is a p with heat transfer or how u guys call it.

I just found the thermometer, will try checking the condeser for blockage tmr. Saw ow to do it in the YouTube link. Though sure its not the fan rotor that came with it, that is there now .

I also noticed something on the compressor. There is this free wire with a socket, i asked the guy why thats not fixed. He said no need, not doing anything. I was like oyinbo wey put am there know y. He said the main thing is connected already. Thats typical naija techs.

Look, there isn't much to do in this case, just get the fan for your matrix, (I am very sure it is the fan), make sure it has all the connectors, remember its speed and power are computer controlled (duty cycle) then put the original compressor, that is the one that came with the car, then vacuum the system, add one small can of oil, I have forgotten the weight, it is just the small can, then according to the service repair manual, put 500g, that is half of the that long can of refrigerant. 1000g.
Measure the can while applying it until the weight remains 500g, that is that 500g is in the car AC system.
Put the can on a pair of scale, the shake it from time to time. You know the car must be on.

prince088:
Yes i can. Thanks

okay.
Here is the link, download it

https://m.thepiratebay.se/torrent/6640072/Car_Repair_Manuals.

when you download the torrent, and load it up in your p2p client, the deselect all, scroll Dow and select the 2003-2007 Toyota matrix, then, download the main file as usual, except you want to download for all the cars it's just 22gigs(lol), if not download ONLY the one for your car.
Sorry for the long wait, I was chatting with friends, don't worry about the lack of seeders, it is just thepiratebay people that have not updated that page.

prince088:
The fan as failing. Sometimes u av to turn with ur hand. And it was not fast. So had to replace. I can not say thr AC was very Ok. Cos i expected it to be cooler. But issue is i don't know hiw matrix AC is, so can't compare. The front side had an accident though which mark can be seen on the cindenser. As a a depression. Check and airbag light on only.

Okay, get an original matrix fan, and I will prefer if you, use the original compressor, vacuum the AC system, and refill the refrigerant using weight measurement.
Okay, In my computer I have the factory repair manual, once I get home I will check it. You also need to scan the car, preferably with a dealer level scan tool.
One more question, do you know how to use u torrent to download files? I mean P2P.

Please I need help on how to solve this Maxima code.

I have cleared the code it came back

I have also changed the solenoid valve, the code did not go.

My mechanic said he will fix it. He told me he will try some things until he gets it, that if I change 100 solenoid valves it will be thesame.

He is charging me 25K for the fix cus he said it is a tough work to do. The car has been with him now for close to 4 weeks. The last time I checked on him, he has the timing chain cover opened down.

Really dont know what to do. He is the only one in d past that have been able to successfully solve my issues on d maxima. All othe mechanics I have used in the past usually leave the worse off than we I gave it to them. But I guess the N25K is asking is way too much plus the time frame.

when did you change engine oil last?

prince088:
Ok thanks. Cos i noticed the on and off takes so long. Fab can keep blowing for long without shutting down on idle.

what happened to the original fan? When and why did you change it? When you initially got the car, was everything working to your satisfaction? What lights are you seeing on the dash when the car is on?

what happened to the first fan?

prince088:
Its one. 03 to 08. I just checked online

you said in your earlier post that you changed the cooling fan, and that the person told you that the fan is not for the matrix, Yes, here lies the problem, the fan is turning too slowly, because well read the following excerpt
"Input from the engine coolant sensor, ambient air temperature, vehicle speed sensor and other sensors may be used by the PCM to determine when the fan needs to be energized. On applications that have variable fan speeds, the PCM generates an on-off duty signal for the fan motor ("pulse width modulation" that causes the fan to run faster or slower."
You need a matrix cooling fan, not an adapted one.

prince088:
Ok thanks. Suppose fan blowing wrong direction will the engine not over heat? Also i put a piece of paper on the condenser and it sucked it..not so sharply though. Sucking is weaker in the areas away from the fan. Watching the vid now.
Will update

there are usually two fans, one for the engine the other for the ac system. I believe that is the source of the problem, you only have one fan. What happened to the other fan?

fortunately it was easier done than said
here is the link for using the infrared thermometer to check for blockages, if you find non then your fan may weak or in the wrong direction.

for tunale

prince088:
Can normal home infrared thermometer do the job?
U need to relax and communicate like the others. All this side jabs in unnecessary. Besides i didn't say i wanted to change the fan and condenser.

Explaining the symptoms, and also what my AC tech guy said. I came here to seek more professional advice instead of changing this and that.

Thanks

But you started it, I tried to explain how the ac system works, but you rebuffed my help saying I did not answer your question, you only needed what to do to make the car interior cold. You must understand how the system works and how each component works and what it does so that if it is not doing its job then you find out why and what went wrong.
Just any infrared non contact thermometer will do, the one that has something like a laser pointer. There is a video on how to do that on YouTube. com, Let me search for it, I am using a phone to type, exercise patience.
