GTM stage 2 Air Conditioner Problem?

How cold was the A/C blowing out of the vent? All this information would help us help you.

As for us not calling you back, if you called once and for some reason we missed your call, call us again. I'm very accessible by phone.

Don't take this as me trying to give you a hard time, but everything I'm asking is for a good reason. There is a certain process of trying to diagnose a problem that must be done by the letter, otherwise you end up wasting a bunch of time and money.



I'm not taking what you posted as you saying that our kit is faulty, because there is no reason for the A/C to completely shut off even with a front mount intercooler and oil cooler in front of the condenser. Yes, it could hinder it a little on a super hot day, but what you are describing is that the A/C is completely shutting off and that is a big difference.

Here are some questions.

1) Was the engine removed from the car when the turbo kit was installed?
2) If yes, was the A/C system evacuated for a minimum of 45 minutes to an hour at 27inHg of vacuum?
3) If it was not done or there is a doubt that it was not done, then you should consider taking it to an A/C specialist and having them completely vacuum out the system and recharge it. That should run you less than $100 or so...much cheaper than throwing parts at the car.
4) Verify your coolant temperature even though keep in mind that the factory gauge is a dummy gauge and is not very accurate. You can't rely on how many dots you are seeing. Hook up your Cipher cable, drive your car and try to establish at what coolant temperature the vehicle is shutting off the A/C. Also, when the A/C shuts off, pull over, open the hood and see if your compressor is cycling and both of your fans are blowing on high speed. If the compressor is cycling and still there is no cold air, it could be as simple as moisture in the system or a problem with the receiver/dryer.

Do that and get back to us. These are simple things you can do easily to determine the root cause of the problem.
