Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.

I HAVE A 2001 DODGE DURRANGO THE DEFROSTER IS NOT BLOWING ANY AIR OUT OF TOP OF DASH BUT SEEMS TO BLOW OUT OK ON ALL VENTS AND FLOOR


it sounds like the switch lever for the vents, floor and defrost is not switching the vent door that goes to the defroster hose. You need to pull the switch consol out loose from the dash and follow the cable for the defrost that goes to the hose for the defrost. You might also have a broke switch that won't pull the cable enough to open the air for the defrost hose.

1988 1500 series half ton. Air vents to mid dash and defroster won't open up. Heat and air blows on the floor only.


It sounds like the door on the defroster isn't opening. Check for a vacuum leak and also check the temp.control valve this should have several vacuum hoses coming from it. This valve controls all the doors, Bi-level, Defroster, and Floor positions.
