Rear heat help

[behindbars1544]

One of the bugs I'm trying to work out of the 05 Yukon I just bought last week is ice cold "heat" coming from the rear vents. I know there are 2 actuators and one module back there that usually go but when I removed the rear panel to access everything today I noticed one actuator was missing. I know the part number for the module but can anyone tell me the part numbers for both actuators? It's an 05 Yukon XL slt with heat and A/C controls in my overhead counsel and rear of me center counsel. I also have the digital climate control head unit with auto feature if that makes any difference. Rock auto lists 12 different parts and I don't know what the correct, most updated part numbers are.

Thanks Guys!!!

I don't have them handy, but I found them by using the parts lookup from Advance Auto.

The expensive one is the one that controls the air temp. I need to fix my truck one of these weekends when I figure out how to get to the modules. Did you have to remove a lot of trim, carpet, etc to get to the rear A/C box?

Nope, Just removed the rear speaker panel and removed the large "wall" panel for lack of better term. Wasn't bad at all.
