I have a 2000 GTP supercharged car. The A/C is dual control and has been working fine so far until one day it went warm on the drivers side and stayed cool on the passenger side. By the time I went to the mechanic both sides were warm. I had it recharged which worked perfectly for 5 days when the whole system went warm again. The heat workes perfectly. He checked for leaks but couldn't find any saying it was the evaporator that was leaking. I am REALLY hoping this is not the case and maybe it's a sensor? I did have a sensor replaced years ago. The other thing that might have affected it was I had water pooling on my passenger side which could have effected the system. There are no codes, no warning lights and the fuses are fine.
Any ideas?
