ok I have a 2005 monte carlo I bought with out a warranty and I was driving home (i live 100 miles away) and it was getting cold so turned on the heater and hot air comes out passenger side but cold air on drivers side. Now there is nothing wrong with the doors or the blower they work fine,only problem is cold air on drivers side. This car only has 63,000 miles on it and it is Tony Stewart modol. can some one yell me if it is the contrl knob on drivers side or maybe the cabel that goes to the control or to heater control. The lever on the control works smooth no sticking or anything both sides feel the same. Tanks one cold blooded drive.
