On my '95 Ben 525I the driver side does not blow as cold as the passenger side.the only time it does is when the defrost lever is on, and at the same time the driver side defrost vents blow hot while the passenger side defrost vents blow cold. The a/c compressor has been replaced and the clutch fan as well. Freon has been checked.... no leaks and psi is good. Any help would be much appreciated. Next step is the dealer $$$$
