2012 Tahoe Climate Control Upgrade from Manual to Automatic

[LRod]

Hello everyone. I have a 12 Tahoe that was outfitted with the manual front Climate controls. I purchased the automatic or button climate control. The pins in the back do not match. Does anyone know of a company that will make an adapter or a connector that will connect to my current wiring harness and work on the automatic climate control? I have tried connecting the pins in the back, but I end up with the defroster being the only option that works and the dash's outside temperature sensor states Null or no sensor connected.

Please help me.

I believe the actuators are different Lupe and the new controller has to be programmed to your vehicle if you can get it wired up correctly. Do not know about adapters but suggest you get wiring diagram from AllDataDIY subscription for your project.

It will not work without ALL the temperature sensors in place.
