Question about 2003 GMC Yukon Denali
There is a small motor between the rear air vents inside the headboard that runs all the time when the car is turned on. What does this motor go to and why does it run all the time?
Is the "Rear Air" control switch above the driver seat turned to "Rear" if so, turn it to "off" or Front and you can control the climate for the rear cabin. If this does not work, then a relay may be stuck.
