2007 LBZ defroster quit
My windshield defroster stopped working. When I push the button it stays on the dash vents. The blower motor works but door is not moving to switch vents. Is their a common problem to look for? I read on another forum that there is a HVAC fuse in the under hood fuse box to pull and wait 30 sec, the replace the fuse, turn the key to on position and wait for the doors to re-calibrate. Thanks in advance.
