2007 Yukon

[Handbells]

I have a 2007 GMC Yukon. The air temp control was cutting out every once in a while over the last 5 days and now appears to have quite altogether. I'm looking for advise on what to start looking for as the cause.

Does this have dual zone temp control or single? Most likely the problem lies with the temperature control door actuator. Small chance that there is a problem with the door itself. You can remove the actuator and try and manually move the door to verify that the door is ok and the temp changes.


Handbells, huh?

My guess would be the actuator just by the hump under the dash on the passenger side. This is the one where it's difficult to get the last screw of the cover off, then I had to grind down shorter a 5.5mm socket to get the actuator mount screws out.

Yes, it is a dual zone temp control. I didn't get a chance to follow through and check it out yet, but have every intention on doing so.

lol...are you familiar with handbells?

Haha...yes. I was in a 5 octave choir for several years, played anywhere from middle "C" down to C3, including chimes, mallets, ect...it was fun.
