Just an FYI, I had warmer air coming from the passenger side vents while the AC was on full cold. Drivers side was fine. Two days later at the dealership for diagnosis and resolution to issue, dash disassembled and every valve, servo checked.

They finally discovered the AC was low on freon. Recharged AC system and cold on both sides. Fortunately, No Charge.

The above statement should tell you something about their abilities. AC not working, and finding out refrigerant is low as a last shot? lol.

 

I had the same issue and rather than take it to a dealer I just went and got some freon. No more issues...Ice cold.

 

Mine is blowing plenty cold but I've been trying to chase down an odd noise in the back somewhere. I thought it might be the CD changer but it seems like it's the 4zone rear passenger blower. It only did it sometimes, turns out it only makes the noise when it's running on low. Guess I'll add it to the "to-do" list.

 

They should off started with measuring low high pressure line
