Hey...I have a 2000 Monte Carlo that is having some air conditioning problems. The air gets cooler on the passenger side than the driver side. of which neither side is as cool as it use to be....
We have replaced the climate control unit from a junkyard, so maybe it was bad too, but it still is cooler on the passenger side.
Any suggestions as to what it could be besides the climate control unit?

Please help....Hiprz34
