2004 Buick Rainer

I can’t get the A/C or Heat to come out the front vents. The vents are open, it will work on windshield, floor, and back vents. I have checked the fuses and none are blown. What do u advise? If not to complicated I would like to do it myself. Also what part would I need and what would that be called?
Thank You,
Velda


This sounds to me like a failed mode door actuator. Its failure is so common that Dorman has come up with a better direct replacement version.
Part you will need: Dorman 604-110 Air Door Mode Actuator
