Chevrolet Repair: 2000 Impala Climate Control, climate control, scan tool

Question
My 2000 Impala AC is cooling well on the passenger side, but the driver side doesn't cool good. Do you have a clue as to how this can be fixed. The heat can be controlled on either side.

Answer
sounds to me like the temp actuator for the drivers side is bad.  This is located behind the dashboard assembly.  once replaced the computer for you HVAC will have to do a relearn procedure with the scan tool at the dealer.  These heater control modules have never gone bad in my career so that's why I'm eliminating it
