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.

Thank you for your answer. It looks like a lot of work, but not very technical. Would you agree? Also, where is the best location to find the exact GM Replacement part at the best price? I am looking for a "Auxiliary Air Temperature Actuator" correct?

Dorman product
Check with your local part store supply if they carry it
Check and make sure both heater hoses hot before taking it apart
And if so actuator is to suspect
Not a technical job at all and can be done with patience

BMRFIXIT you answerd my question 3 weeks ago regarding the Temp Actuator on a GMC Yukon Denali SUV replacement. WHen you refer to the quarterpanel, you are referrin to the internal trim and not the actual car quarter panel on the exterior correct. I am not finding the screws for the 3rd pillar to remove the interior plastic trim. Do you have any pictures you could email or send to me? Thanks. Glenn
