My air conditioner is blowing semi-cold on the passenger's side and warm on the driver's side. I have checked the fuses and all seem fine. Could it be a relay switch?

Thanks for the info!

Its an indication you may be low on R134a refrigerant. Check the pressure with a gauge on the low side port. The pressure should correspond to the ambient temperature. I don't have the figures off the top of my head. But I could check my GP service manual for you.

i have had same problem several times...my car has had a leak and every time it gets charged it leaked out a day later....as it lost freon i noticed the drivers side was warmer than the passenger side, and eventually it lost all the freon and both sides got warm....check the pressure of your freon and if needed charge system...if this happens again then you probobly have a leak...if not there may be a problem withe the doors under the dash that control ac or heat....
