Most likely,thank you for the replies.

You welcome sir.

Thank you Oga Mosbus. Deeply appreciate you sir.

You welcome sir.

idtwo:
Thank you sir for your prompt answer.
A technician told me that compressor oil seal for cars that are automatic cannot be replaced if the leakage is from the compressor, that one must consider replacing the compressor either with another automatic or 'work' in one from a manual tranny. Vehicle in question is a Hyundai sonata 2009. And cost of the AC compressor is quite high.
Pls what is your view on this? Thanks again.

The technician is right,even when buying a tokunbo automatic controlled compressor,you have to be very careful.
Reason is you don't know the millage of the car,where the compressor is dismantled from.
Such compressor is 50-50.

Well done Mosbus and thank you for the very educative thread.
Pls does low refrigerant level always mean there is a leakage in the system?
- Can the refrigerant level reduce without any leakage in the system?
- What should be the ideal refrigerant pressure for a car like Hyundai sonata?
- Lastly, is it advisable technical-wise to 'work' a/c to a car that didn't come with a factory fitted a/c?

1,once you have low refrigerant in the system means there's leakage.most likely from your compressor oil seal.
2,idle low pressure without putting on the air conditioning is always 120 and above depending if the system is single or dual evaporator.
3,yes, that's if the technician has the electrical digram,because every car above 2000 model has air conditioning space to install,and the only way it won't affect your car is if you install the thermostat, pressure switch and relay etc,in the right positions.

nnamzy007:
that's the problem,as industrious As Aba is,there is no single standard car workshop here let alone AC technicians. Anyone of you that opens a standard workshop here will be making top dollars. Plenty people are in my shoes. By the way,yes I just refilled the gas and no it wasn't vacuumed. Heck they don't even know what vacuuming means.

They have over refilled the system with refrigerant.your car takes 1kg of gas, anything above that is a problem.

nnamzy007:
chief,i drive volvo s60. My ac cools very well when am not accelerating but as soon as I accelerate no matter how slow,i think the compressor disengages cos I don't feel the cool air no more..Thank you.

Did you just refill the gas,look for a good technician who has advance scanning tools to help you run diagnosis check on the air conditioning.

kaz4sure2015:
Hi Mosbus , please what could be responsible for my Lexus Es350 not to cool when the temperature is high in the afternoon but normally cool very well in the morning.

I also noticed that the Driver side doesn’t cool as much as the passenger side in the afternoon and it will only pick when I accelerate

Thank you

Low refrigerant in the system, check for leakage and also check your radiator fan.

shina101:
Please I need your candid opinion also help too, my Toyota Corolla 09, the AC gets cold very early in the morning till like around 11am when the sun is up, then once the sun gets really hot around that time, the AC kinda only blows air and little ac, especially when am in traffic, then evening from 7pm when the sun has gone down the AC gets really cold again that I ve to reduce it to the lowest. My ac guy is now telling me to buy a new compressor. Please help a brother before this guy kill me.

cc mosbus

Those you ac technician has manifold guage,if he those tell me to help you check the pressure reading when is sunny.
What's is the level of your temperature guage.

sharks776:
Good morning, pls help me with this issue.
Firstly, when the AC failed, the repair guy suggested that we convert it to a manual set up. After much argument I agreed.
We changed the compressor, condenser, expansion valve, pippings and evaporator but worked but failed after a week because the replay was exposed to heat which made it to fail resulting in a bunt compressor.
He suggested we fix the compressor but I refused and insisted that we revert the system to it's initial design.
We bought a new chinko compressor for 120k, flush the system and filled up with gas again. It worked but only for half a day. Kept having gas leakage here and there until when all leakages were fixed.
It's been over 3 months now and we have NEVER ENJOYED it for a single full day. It works only when it feels like and stop working after 10-15min and starts to blow hot air
Sometimes it can go for 3 days without working and even when it does, it never cheals very well like a freezer
I tried other ac techs but all I keep getting is to convert back to manual system which I refused.

You need a good high tech to scan the AC system,your car is likely having electrical issue which you need to fix first before anything.

peaceland:
Good people,
Noticed of late my ac cools better when the recirculation is off. What could be the issue please. 2009 Accord 4 plug. Thank you.

I hope they haven't interchange the plugs of the servo motors, because normally your AC should get cool better when the recirculation switch is on.
You need a good AC technician to help you check, possible the servo motor is working in the reverse direction.

Gracesofar:
Bros mine started having issues last week, tot its the gas and when I got to where they buy the can AC gas the guy feeling it no even check he just say e be like compressor get issue. It blows hot or normal air doesn't get cold.... What are the possible problem I should prepare for

1,low refrigerant which means you are having leakage in the system.
2, electrical issue.check the fuse or relay.
3, faulty magnetic coil.

totit:
Sorry about the incomplete sentences.

It's actually the AC, it's working but blowing heat instead.

Mine is working tho but it's blowing heat.


And lest I forget, it's Nissan Xterra, 2000, SUV.

Pls kindly give clear details of what the problem of your car is.

Fill free to contact mosbus,if you have any issue with your car air conditioning.
You can also send air conditioning error codes

Cc: Gazzuzz, Mosbus

When changing your compressor and condenser.
You also need to change the high pressure hose.
The high pressure hose is nylon quilted internally,after many years of usage the hose get blocked internally.
That could be the source of your compressor damage.

Thanks for your patronage.

Mosbus biko clear me for something.



My volvo AC get one issue, sometimes the AC no go pick, dey cool. na only fan go dey blow.

I notice say e dey usually happen if i no switch the AC off before i switch off the engine.

sometimes if i park for hot sun, when i start motor the AC no go pick (but no be all the time this one dey happen)



but i come discover say if i plug OBD scanner, clear the ECU the AC go pick ,start dey cool again.

as in e dey work steady, normally. dey chill well sef.


abeg wetin you think say dey cause am?

Look for a advance scanner and scan the AC system.
What ever code it gives you,send it to me.

[quote author=funkymeky post=86187317]Please @mosbus do you know any good Ac technician in port hacourt ?[/quote


NO i don't

manual or automatic depends on the issue with your car,people don't know the difference within both compressor,all that really matters is every car has there compressor capacity either variable controlled by sensor or magnetic controlled.
Some car are designed to run with e.g 1h.p sensor controlled while some are designed with 1/2 h.p all you need is make sure the automatic or manual compressor are the same capacity, there's a template on every compressor for you to know the capacity.
In additional sensor compressor voltage varies isn't stable like the magnetic coil controlled,get a relay to constant the voltage to 12V DC.
1,if you have a contaminated system, automatic compressor can't work again.except you overhaul the system.
2,if your radiator fan speed isn't working properly am sorry automatic compressor won't work.
Because your fan speed is controlled by your ECU(brainbox),which is very hard for so many car owners to believe.
3,the only reason why you can use automatic compressor is if all I mentioned above is fine,because some times due to age or long time use sensor controlled compressor can fail,you can change only the compressor and every thing will be fine or sensor.

drisi:
Please is there any AC technician with vacuum pump in Benin city?

Know pls I don't.

autologic:
Somebody has tampered with the ambient temperature sensor located in frontal area of the vehicle ,look for something like this in front of the condenser ,seems it has been disconnected,just connect it back

The sensor might be sprayed with paint.

1,Turn your engine switch on (IG)while pressing the A/C control 'AUTO" switch and the R/F (recirculation/fresh selection switch) simultaneously.hold both switches until the indicator check screen appears.
If you perform this check in a dark place DTC 21 or 24 may be displayed even though the system is normal.
HINT.
Refering to the DTC code.when ever you see DTC 21 on your screen,it means B1421.
When there is no problems,DTC 00 will display.
2,If the step is difficult to read,push the "UPDr" switch (driver temperature up switch) to read the code easily.
#Off switch to finish panel diagnosis.
3, Clearing the error code press the "FRONT DEF" switch and "REAR DEF"switch at the same time.

It more about the skill level of so called AC technician than the gas .
How many so called -AC technician knows about refilling AC with correct quantity of refrigerant and oil that manufacturers recommend cos most AC guys will refill till they are satisfied that the car is car is cooling well and the obvious fact is that if u refill beyond normal quantity u will introduce liquid refrigerant into the compressor suction side and sludge the compressor and that will spell doom on the AC system .
how many AC technician knows the standard troubleshooting of AC using manifold guage to read the high and low side and diagnosis correctly
How many of then know about correct procedure for evacuation and vacuuming of AC before refilling talkless of owing the machine.
How many AC technician knows about theory of gas pressure temperature relationship and saturation temperature and the application of this quantities in their daily AC work .
So many ignorance on part of the technician that is killing the compressors and pushing the blame on the gas .
How many AC technician knows about the signaling and module to sensor relationship of modern AC system architecture but will convert anything they see to the ancient manual system they understand if they see any modern design they are not familiar with .
All these are minimum criteria to be satisfied before someone can be patronised to fix AC
Or else frustration will be the result .

You are very right most AC technician in nigeria doesn't know how to refill Car AC.
Talk less of knowing what vacuuming a system means.

Hello do you have any AC technician in aba,abia state
