Question
I recently had our van air compressor replaced.  It worked fine except it was clear the compressor was going and had to be replaced.  After getting it back the driver's side A/c is warmer than the passenger side a/c.  Now a week later the rear a/c zone is completely warm.  It wont blow any cold air.  It actually is not even cool.  The repair shop assures me that it has nothing to do with what they did, that they were never on the inside of the car.  They said it seems like some type of climate control.  The passenger side blows nice cold air.  What could this be!!

Answer
U have a leak in the system    if U have a van year from 01 to 05 they are bad about leaking at the condensor   when the freon is low U will get warm air out the pass side first then it will be warm all over. Have the shop check for leaks.  Oh BTW  the compressor went out due to the freon being low and oil leaking out so it locked up the compressor.
