Hey, my name is Dusty and I'm one of the auto experts with RepairPal's Car Genius team here to help! It sounds like you may have an issue with the temperature blend door actuator being stuck and in turn not moving to the proper position. You could try to run the EATC Self-Test (Electronic Automatic Temperature Control) module, to see if that helps, while retrieving any faults stored in the EATC at the same time. The good news is, a quick Google search is all that's needed to locate the procedure! If you'd rather have a RepairPal Certified shop take a look at it or if you have any other questions, give us a call! 877-913-1554
