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

  1. trying to place the mode door in the middle of its travel position, but it won’t stay in position. Just flops right back to where it is. How do I hold its position in order to install the mode activator ????
