I have an 04 yukon with auto climate control...The vents work (meaning there is air that comes out), but when I select feet, or the chest area, nothing happens it just stays the same...When I also select defrost for the front window no air comes out of the vent...Is it maybe an actuator problem?..I dunno...Any suggestions...Thanks

With the fan still working I would assume the device that redirects the air is not working (fried, fuse). Not sure how to repair it or what exactly that which needs repaired. Someone else will chime in.

 

I tried swapping out the fuse with a similiar one and still nothing happened...The same problem still exists...Thanks

sounds like actuator to me.

 

+1 I'd guess it's the mode actuator...

 

Right on...Thanks guys...
