An lx 350 Lexus entire system was flushed today..while the compressor and the condenser was changed as well..
The system has turned black, most times when you notice your ac deteriorating, it's cause of this..you will start to notice that it is not cold when it's in holdup or static but will be blowing when it's in top speed, it will continue to deteriorate, no matter what you do..the solution is new compressor and condenser..the evaporator and the pipes will be flushed.
Often time we can change the compressor only and Flush the condenser..but the best practice is giving the new/tokunbo compressor a new condenser

I once on my AC and I smelled wire burn and next thing was smoke from under my stirring. An electrician changed the wire and the next day same thing happened and I returned it to the same guy. This time he bought a stronger wire and rewired the burnt wire (a single wire that went to the compressor) since then it has not done that but I have also reduced hand in the way I on the AC out of fear.
My fear is that the guy never told me the cause of the wire burn and he just went ahead to change the wire.

Hello guys, my name akintunde aka realsleek, i am an auto. Air conditioning specialist running an outfit called SUBZERO ,that caters to all kind of AC issues from diagnosis, installation, repairs and sales of Spare parts ..based in ibadan.
Please feel free to discuss any AC issues and i will do my best to give answers.. thanks

I did an engine work on my car recently but yesterday while driving home I noticed my temperature rose past d middle. Quickly parked. I noticed water had drained on the front passenger side with d rug all soaked. Had to call d mechanic who worked on d engine. He said d pipe carrying coolant from the engine to the ac was leaking hence d soaked rugged which drained d coolant and caused overheating. He bypassed the pipe. Pls what's d implication of this cos I intend mounting my new compressor and condenser this weekend. My little browsing online shows no effect on d cooling of d ac just dat u might have a blurred windshield when driving. Pls advise me cos I found out that tracing and fixing d leakages might be expensive. It's an Honda Accord 04

I observed my ac was not cooling effectively. I took it for diagnosis and was told it had leakage, so he sealed the leakage and refilled the gas. After a day or two, it completely stopped cooling. What steps can I take to get my AC system back and running? Secondly, how do you determine that your compressor(automatic) is working? Thank u.

There still leakage yet to be fixed and it wen all leakage has been successfully fixed then you can have the system runing well.
Secondly, how do you determine that your compressor(automatic) is working?
Nice question
cos the vdc (automatic) compressor seems "engaged " at every point in time so it practically impossible to know wen compressor has been triggered on checking physically as opposed to the manual type .To determine this ,you will need to make use of ac diagnostics tool : Ac manifold Guage and you must be trained to be able to interpret the readout. (That will be a topic for another day or u can check online )

I guess he too couldn't figure out the root cause which is reason for his silence and he can only fix it the way he understand .
The common reason a cable get burnt is due to overcurrent and root cause can be due to the cable getting shorted to ground or using smaller cable Guage or load problem .If your cable size is ok then find a good technican to check out for potential short to the cable and the ( load) compressor too.

I don't know if this is clear enough. That circled place is where d bypass was done.

It actually the heater chamber that was bypassed .
The only downside is that u won't have heater if u need hot air atimes in your car chamber .

Thanks. Exactly what he told me. I guess I can manage it like that.

The leakage is still there. Look for a competent AC technician to look into it

The pipe carrying coolant from engine through radiator to the heater ..(back and forth) is the heater system, quite different from the AC cooling system. I'm sure all he did is crossing the heater. So no more hot water coming inside the heater, if you notice the heater side of the AC isn't working anymore. So no other effects other than heating system won't work again. Ok?
So go and install your new compressor and condenser without worries.
Pls get back to me if you HV any other question or you are not satisfied with my answer

To answer the question how to determine bad automatic compressor is still working..there isn't much you can do,other than trying to see if the compressor has not locked/knocked by rolling the clutch plate with your hand, if it's hard, the compressor is a goner..
Otherwise, there is no way to know if the compressor is working, all you can do is put gas, if it's not cooling at all at all, then it's gone or if it's failing, cool in sometimes, fail sometimes, then start work again some other time, you have to get a new compressor.
If it's manual , you can pump it, but an automatic doesn't pump cos it runs on electric sensors.

Beware of rewires o..find competent auto electrician to find where ur issue is ,it may not even be related to AC. Or if it's AC, there is wrong electrical connection

Today I had to find the leakkge of a Highlander 2012, only to discover the whole pipe under. Has rusted. So we had to relay the new liquid side and discharge pipe altogether..it's no easy task but it's done.thank God

Good day sir ,I really appreciate ur good work..pls sir I'm having issue with my 05 corrolla verso ac..at times it work perfectly well but most times it doesnt cool till you fire or on the high way speeding...the technician I took it to said my compressor censor is bad that I should change it to electric manual compressor ..that it would fit perfectly and won't require any construction..I don't know what to do..pls what do u advise ..he assured that it will work perfectly well..is it advisable to put a different compressor?Will it affect the fuel consumption?

You won't also have auxiliary cooling fan.. only the wise ones can relate

I drive a 2004 sienna. I got it as a tokunbo few months ago. It has low cool wen the car is on idle but the cooling is more wen in motion especially on a long trip. Although the cooling is still not as cold as how a friends car ac chills. Wot cud be the possible cause.

You might have a compressor that is losing compression due to the fact that it is going bad ,or the condenser ability too dissipate heat is impaired due to airflow issue , dirts or clogg on the condenser.
To fish out the real culprit,take the vehicle to a competent ac tech that can skillfully analysis with manifold Guage to troubleshoot for u .

Your compressor is having low pumping but in the mean time ,you can go to a car wash and ask them to flush the condenser but have it in mind that you are changing compressor..
You can also check the car slow...maybe the slow is too low..

I bought a new compressor, refilled gas ,also bought a new cooler for my car. New thermostat was also bought and set but acc is not chilling . It's not cold as its should be in the car. What could be the problem ?

What killed the old compressor? And why changing only the compressor?cos if the compressor has developed wear and tear internally ,debris from the it will get stucked inside other ac components and if those components are not changed and the systems as a whole not properly flushed , debris inside those components will be murdering any new compressor u keep adding to the system .
Way forward : find a technican that can make use of ac manifold for diagnoses to confirm the issue with the compressor.

Thanks but that was done before buying a new compressor. The condenser was also removed and flushed. The problem is that it's not cooler than its supposed to be

The bolded above is where we always miss it .A condenser cannot be flushed do outright replacement for a condenser .

This is the problem I have with my C200 MB car.the ac is giving me problem.i have repair it two times now still this problem.i am in Enugu state

Pls buy brand new compressor online oem from aliexpress,buy condenser 15k,buy valve. Buy original coolant, forget story of buy tokunbo compressor. Do u have an idea how many miles the tokunbo compressor endured before it was discarded as tokunbo in naija. If u wan buy tokunbo buy from ebay USA and ship to naija,or buy brand new direct from aliexpress. U can never regret it,e go last u at least more than 10 years. Dont forget they will vacuum out every if not e go park up again.

Just very unfortunate that very few ac technician that really understand and can really analyze the ac system, the the rest are just installers ,fitters and part changers whose hands are always faster that their brains.
If you keep repairing and still no headway then it means root of the issues is yet to be identified with is the most important job of all .Don't buy or change anything yet if the root cause has not been duly identified 100% so that it doesn't end up in premium tears.
Let me start by asking u to list the problem u are currently facing with your ac and base on that i can advise u the next route to take.

God knows how much a new benz compressor would be by now...last time u checked it is well over 200k.
Speaking of tokunbo compressor, how many ac clients can actually afford new compressor. some car compressor price are just over the bar...unless u want to buy china..it all depends on the car Sha.
And benz condenser for 15k??
