Hey guys,

I'm experiencing a rather perplexing issue with my 2008 MCS. I just had my car in to have the clutch replaced and had a whole clutch kit done. When I took the car down, I used my AC and it blew nice and cold. On my drive home from the shop today, the AC blew warm air and never got colder. I know the AC compressor works because I could hear it turn on and see the RPMs increase at idle. Any ideas as to what would be causing this? Is the AC impacted by the transmission removal?

Any thoughts would be very much appreciated.

Depending on the shops R&R procedure for the clutch, they could have lost the charge on your AC. You can get by without losing the charge by swinging the condenser to the side to remove the front core support. They could have removed the condenser entirely, thus losing the charge and not refilling. I would check your AC charge.

Thanks for the response. Do you know the best way to check the charge? Or could I just get one of those AC Pro bottles?

if they swung the condenser to the side, it's possible they could have cracked it or put a hole in it......but if that was the case, the compressor would not kick on due to very low or no refrigerant in the system at all

do not get one of those AC charge pro bottles with the gauge....those are junk.....if you are going to try and fix the AC system yourself, you will need a good set of pressure gauges to connect to the AC low and high side pressure ports, you will also need to know what you are doing and looking at with the readings........if you are AC challenged, best to take it to a shop that does AC work.....

Or go back and complain to the shop that did the clutch and see what they did wrong?

Hey, thanks for the suggestions. If you don't think it is a low refrigerant level then, any other ideas as to what it could be? Thanks for the help!

It still could be low, most AC systems have a "window" of when the AC works.....if it's too low, the compressor will not turn on.... do you hear the radiator fan working when you turn the AC on?

If the system is low, it will blow warm air....the system charge is a specific amount, don't just add anything to the system, you don't know how much is left inside, and you don't know how much you are adding

You may end up doing more harm than good by messing with what you are not sure about
