Air Conditioning with Climate Control on 2006 Buick Rendezvous

We can not get even temperatures on both sides of the car. Temp outside 60 degrees. Have to set thermostat in car to 76 to get any heat. Driver side really cold, passenger side blowing massive heat from floor that is very hot. Passenger side is turned all the way to coldest setting and still getting heat while driver side is getting cold air.

Your climate control system needs to be scanned. There are several doors and sensors that could be defective.
