I have an issue with the AC blowing warm/not very cool air on the driver's side. The passenger side is great! About 6 m ago I had a new compressor installed, It worked great for 3m then recently started doing it again. I have noticed that after 30 min or so if I am driving around running errands and the car is being turned off and on, after the 2nd time of being turned off/on, it starts working a little bit then all the sudden starts blowing warm again. Help!!

 

This problem is usually associated w/ low charge. You may have had a leak that has never been repaired (original problem!) and has again leaked down causing asymetrical cooling.

Suggest having a AC system leak inspection. They will inject HP nitrogen mixed w/ refrigerant and look for bubbles and check w/ electronic sniffer for leaks. A 3 month leakdown would be a fairly sizable leak and should be easily detected.

good luck
