Hi I have a new to me suburban and the rear climate control when you start the vehicle goes right to low. If I change the temp setting it stops and works properly. Any ideas? I’m thinking of swapping the controller but before I do I want to make sure I’m not missing anything. Again it only does this when you start the vehicle. Thanks, trying to upload a video.

 

Welcome to Chevy - please post your vehicle information for help!

 

You have a real workaround - change the temp setting - I might just keep things as they are now !
