: Vent Selector not working

11-30-08, 10:23 AM
I have a 2004 Escalade ESV, and the heat will only come out the front vents. If I select for the heat to come out the floor or defrost, nothing happens. The heat still blows out the from vents in the dash.

What can I check to fix this? Is there a servo that controls the vents? If so, where is it? Any help will be appreciated.
