Pontiac Repair: dual climate control, dual climate, climate control

Question
The dual climate control in my 98 grand prix when turned to heat blows out cold on the drivers and hot on the passengers side do you know what is causing this? Thanks

Answer
Hi Paula:

well it can be a few things. does the temp flash on the head when you turn it on? If so the control head sees problem and has stored a code in the controllers memory. more than likely the tempature actautor has gone bad on the side that is blowing cold air when you have it set to hot or the door is jammed up inside the heater box. It can also be a tempature sensor has gone bad too but not all that likely. Good luck :)
