Volvo: Volvo A/C, 2000 volvo v70, volvo v70

Question
Last September I purchased a 2000 Volvo V70 with 75K.  In
April of this year I had to replace the A/C compressor.  The
problem I am asking about is an out-put temperature
differential between the driver and passenger side vents.  
The passenger side is cool but the driver's side temp is
intermittently warm or at least warmer than the other side
even when the temp is set at max cool.  The option to mix
outside fresh air is off, it doesn't seem to make a difference
anyway.  The system was recharged 6-29-04 and it
appeared better for a couple weeks.  The dealership  
checked for leaks 7-27-04 and found none.  
They said all vents were blowing evenly, they were unable
to duplicate the problem.  It happens consistently  but not
all the time.  Any ideas?  Any information
would be appreciated.  Thanks!

Hello Chris! There could be a problem with the climate control module or the damper motors that control tempeature. The car should be equipped with dual climate control. I would also re-check the a/c system for leaks or clogs. There could be a fault with the evaporator.
