GTM stage 2 Air Conditioner Problem?

LafitteZ

Im also not saying the turbo kit is faulty. Im saying its kindve funny that alot of us where it is hot is having this problem. It happened to me the day i picked the car up last summer and its now happening again this summer. Its never happened every before this kit. What i meant by help was for one if you ever heard of this problem. So with that being said the ac pressures seem to be fine. I personally think it has to do with the heat build up between the radiator and fmic. I have a big 34 row oil cooler in there also. If its not a mechanical problem do you think it may be just an airflow problem?

It is hard enough to try and diagnose a problem over the internet, so in my opinion, the mechanic saying that it is fine, is not good enough. If he went through the trouble of hooking up the gauges, then what was the pressure like? What was the ambient temperature the day he checked the pressure? 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.

Thanks man sry for the frustration. just a pain in the rear ya know. Im going to see if I can get hooked up with a hopefully decent mechanic around here that i can ask some definite numbers. Z1 I guess has my cable or I didnt get one for some reason. Im going to see if I can get one to see whats going on. This is some stuff I can use. Thanks again ill be in touch.

Great support on the part of the GTM team. Nonetheless, I can't help but file this as yet another potential cryptic issue related to the FI build.

I hope you do get your issue resolved in a prompt fashion LAFittez.

Ha guess this does seem a little bit counter-intuitive. The heat hasn't been unbearable, so I usually just go windows down, no AC. However, I usually turn the AC on at a stop since it gets hot in the cabin and there is no airflow to the oil cooler. I have found the AC fan pulls some air in and helps control the temps.

Even so, I still don't get oil temps above 220, even on hot days in traffic.

Sam has been amazingly accessible to me when I call, in fact, I think I've called GTM about 15-20 time (since my car has been worked on there) and Sam has answered 80-90% of the time.
Sam has amazing knowledge of our cars and has always shared it freely when I ask,
