Cab climate controls don't direction air through vents.

Recommended Posts

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.

Blend door actuators?  Notorious for going bad.  I just replaced one, but it was the easy one which just put heat to the driver side all the time.

 

Rat nest?  Other debris like leaves in the vents?

 

But sorry, I don't know where to start looking...

It should show up on a Tech2. Have it read at a shop and they can tell you which parts are giving you grief, however, the blend door and two of the other three modules require the removal of the center console....means the seat has to come out. Not rocket science, but a helluva tinker toy project.

PaulR0580,

 

Thank you for your response. I will see about getting the Tech2 reading on the vehicle.
