I can no longer adjust the temperature in my car (LTZ model) no matter if I am in or out of the auto mode. It seems I can only get air to flow through the defroster using full defrost the rest of the time air goes through the AC vents.
In auto mode if I turn the temperature either way to the far right or left the fan goes full speed blowing out cold air.
The fan switch works on in either mode.
I am wondering if replacing the entire control unit is what I need to do or if the problem could be something else?

I hate to spend the money on the unit if it will not fix the problem.
Thank you.
