Climate Control Problem '05 GXP
Hi,
I am a new member of this forum. I bought my wife an '05 GXP after a crackhead rear-ended her Maxima. I love the car, even though it was used with 307 miles. It was sold as a "Show Car". It had been driven hard in all of the miles. Tires were scrubbed very well. It has been very good to us and is a total joy to drive! No problems other than the annoying water in the left fog light and the problems with the steering shaft, fixed twice, still a little clunky once in a while.
My problem is that the driver side A/C comes out of the vents warmer than the passenger side.
I have switched the duct temperature sensors, no help. I verified that all of the actuators are responding to the changes in the controls. I am now lost...
All of this was done at great pains in my back and neck, with unbelievable disassembly of the lower dash.
Any suggestions from this knowledgeable forum?

i have the exact same problem with my GXP, the A/C is garbage on the driver'* side, and much cooler in the back and passenger side
i asked GM about here in town since i still have some warranty on it, they said its "normal"

I had the same problem. Warm driver'* side and cool or cold passenger side. About 30psi Lo and 150 psi HI. Really had me baffled.
It took less than a pound of freon to fix. The recharge lasted me about 4 weeks. I have a really slow leak. No clue where it is.

Hi,
The consensus appears to be low freon, thanks a ton! We took the car to Arizona, and the cooling was intermittent, so the low freon seems to make sense with that symptom.
I have a fill system with gages and hoses, but I am not clear on the refridgerant and fill process. I assume 134A is in the system and can be bought in any parts store (I'll check the labels and book to see if 134A is the right stuff.). I have had good results with R12, but I do not want to screw this up car.
Can someone give me a simple process or guide and what the final high and low pressures should be?
Thanks again!

R134 is correct. what i usually do is get the artic chill a/c refill kit. it comes with 2 cans of freon and a hose with a gauge on it when the needle gets to the high side of the green in the gauge your all set

I'm also more familiar with the older R12 systems, but the principles are the same. When I juiced mine up today with about 8oz, the low side was about 34psi and the high side was 150+. As I recall, the old R12 systems ran at about 28-30psi Lo side.
Eventually, I hope the leak gets big enough to find, without spending a fortune in a shop.
(I gave up hoping the leak would majically go away)

An AC system has two sides a low psi side (before the compressor) and a high psi side (after the compressor).
When the Freon leaves the compressor it is a high psi gas that "boils" off with the warm air in your car, and turns into a high psi liquid as it goes to the condensor. As it goes through the condensor it turns into a low psi liquid and the liquid "boils" off with outside air. It then turns into a low psi gas between there and the compressor, once the freon gets to the compressor the cycle starts again.
Thats a snapshot of you AC system and todays lesson on Thermodynamics.
