My 2003 Grand Prix has a problem with the ac, it blows cold on the passenger side but not the driver side. Its not real hot but its noticeably warmer than the other side and sucks on hot days!
I checked the Blend door motor. The motor is good, so I manually moved the door to the cold position. Still the same temp as before.
I put a new climate control in it, and still the not working right. https://www.rockauto.com/dbphp/x,car...C_Control.html
Any ideas of what else it could be?
