What are the chevy traverse defrost problems?

Some of the defrost problems on the Chevy Traverse are the inability of the defrost to work on the top vents, inconsistency in blowing on the vents, and air not coming out at all when turning the climate knobs. Some owners of this vehicle have been able to fix this problem by replacing the blend door actuator. I wouldn't recommend replacing that part unless you knew what you were doing. My best recommendation would be to either call the dealership and ask if there's a recall or taking the car to a mechanic. If you do decide to take the mechanic route, Make sure you take the car to the one you trust. That way you will avoid paying for something you don't need to replace.
