Hi Ya'all, just bought another hummer to match my Limo, I knew it was gonna be a project and it's in the shop right now having the front end rebuilt but in the meantime I wanna throw a couple of questions out there to see of I can get some help. It's a 05 SUV with the Adventure package, and my issue is the climate control. My mechanic (not dealer) hooked up to it and said all the actuators and blend doors do what they are told to do but my heater only works in emergency mode (or 90) so to heat the car you have to use the fan to control the heat. When you hit "Auto" it blows cold, when you drop the temp to 89, it blows cold. He thinks the module is bad or needs programmed, what do you guys think?? This I a 300 module so I don't want to buy one if the dealer can just reprogram it, Thanks!!

 

Hey I have the exact same issue after replacing the module with a doorman model. I cannot get it into the setup mode pushing the On-button and front defrost Button. It does nothing really. Any advice?

 

Welcome to HF. I have some advice. How about do NOT dig up OLD THREADS like this one from back in 2018 SIX YEARS AGO! READ: Old Threads/'Necro-Bumping'

Skip the resurrection, just ask your own brand new question in a NEW THREAD. Please do that and good luck.
