GTM stage 2 Air Conditioner Problem?
 

I had the kit installed at z1 and the day I picked it up we started to have this problem. If at idle or slowly driving around like in traffic if the temperature outside gets hot the ac starts to blow hot air and the compressor doesnt seem to kick on like normal. I have a 34 row oil cooler and vis vented hood and we took the drip pans off so the vents were open and it seemed to help but that was in georgia and winter began right after that. Well ive since installed a csf radiator trying to prepare for the heat and humidity down here in NEW ORLEANS. Well the outside temps are in the 100 range and the ac is blowing hot a heck. The oil and water temps are even better then stock. Theres enough freon in the system so theres no leak or leaks so I dont know what else too do? Any ideas?

bump anyone? GTM Help!

What is your refrigerant high and low side pressure?

I didn't really ask. I just know they are in spec.

When it starts if I idle with the hood up it warms up but the compressor stays on. Once I start to roll or idle with the hood down it kicks off. At night or once it cools down outside it blows cold as ice.

I have the same problem. I just chalked it up to the giant intercooler blocking the air flow when not moving. It works just fine when I am moving even just a little.

It only does it when it is really hot out. 90+

Yea but I'm in new Orleans were its hot all the time and it's my daily driver.

interesting post!

Very interesting thread! I have not had this problem. I have been driving in +/- 90 degree heat lately and have been ONLY turning on the AC when at a stop. No hot air for me...knock on wood.

As same had mentioned, double check your high and low pressure again. We've done a few TT stg2 kits and never seen this issue before... curious to know what seems to be the problem.

I'm having this exact issue and am taking it in to the dealership to have it looked at. It will blow hot if I'm waiting at an on-ramp light, when I accelerate, or if I leave it sit for a few minutes. It takes me five minutes fighting with it until it starts working again. Yesterday was over 110 and it was a nightmare. My oil temps stabilized at about 190-195 driving around and would get to about 215-220 idling. Water "dots" didn't move. I didn't feel like pulling out Cipher to log the exact temps. It is occurring more often when it's warmer.

How does one check this and what should it be?

I really dont think its the freon. My car did it before and now after a csf radiator. I wonder if theres some kind of thermostat or something thats reading the temps extremely high and kicking the compressor off? When its about 100 degrees out side my outside temp gauge reads like 110. Not sure if it has anything to do with it but just an idea.

Sub'd for more info, as i'm saving my $$$$$ to go GTM TT soon.

My car does this every so often usually in dead stop Miami traffic.
