On my E 320 the driver side blows warm air but the passanger side is nice and cold, I took the car to dealer twice and each time they said it needed freon and it's fixed now. They even checked for leaks with dye and did'nt find any. I suspect that a flap must not open or close somewhere in the system but I don't know where. Any help would be greatly appreciated.
P.S. Why the serive dept. at most the dealerships sucks??????!!!!!!
