Question
I have A 2002 Pontiac Bonneville with the electronic climate control system. The problem I am having  is that the driver side of the car will only blowout cold cold air no matter what I turn the dial to. The passenger side and rear work just fine just the driver side is cold almost as if it coming in from the outside.
Please help and thank you

Hi Aaron:

well first oof get the car scanned for codes at one of the big box auto parts stores and see what code(s) are set in the HVAC control module. chances are the temp door actautor on the left side has gone bad. It could also have some sort of a temp sensor issue as well with the left side but more then likley it's just a temp door actautor. They do go bad from time to time on that model car. good luck :-}
