Denali/yukon Rear Heating Does Not Work

[par3eagl]

Can anybody provide instructions on how to replace the rear passenger area's temperature regulator? The heater works perfectly in the front part of the cab. Everything in back of the driver blows cold air. The A/C works perfectly. I have been told that I have a bad "Temperature Regulator"? Anybody with experience with this? I understand it is located in the trunk area of the SUV. The dealership wants 2 1/2 hours time to fix the problem plus $189 for the part. Thank you for any assistance if you have performed this type of repair in the past.
