2006 Sierra, Duramax 3500 crew cab. Electronic control module with individual side control. Air doesn't flow through vents and the electronic module controller for moving air through vents from floor to windshield are not working either. Replaced electronic control module at repair shop. Replaced blower motor and resistor which came with updated harness, blower works fine. Did a reset according to directions from YouTube repair suggestions with no results. I would appreciate some ideas as to what further steps are needed.
