Hello, I have searched for my specific problem and haven't found any insights, so I'm sorry if this has been covered somewhere and I missed it.
I have a 2004 GMC Yukon Denali xl 1500 with the 6.0l engine. I have automatic dual thermostat controls. I was having hot air blow from the drivers side only after a couple seconds of being on ac. I did the relearn listed here, it didn't fix the issue so I replaced the actuator with a dorman 604-111. Violia! Cold continuous ac air on both sides of the vehicle! Yay. For thoroughness, I checked the heat.... Not hot on the drivers side. Gets very hot on the pass side, just ambient temp air on the drivers side. I checked the coolant, and did the relearn process to the new actuator with no better results. I'm lost. I checked the rpo codes on my part to what's listed in the glove box, everything appears to be right... Does anyone have any further ideas or instructions? If it is important I had the radiator replaced about a month ago, I haven't tested the actual heat since then, but the air that came out of the drivers side when the actuator was bad, was definitely heat then, definitely hotter than ambient temperature.
