Heat not blowing out of windshield vent


Put the defroster on and move your temp setting towards warm and youll feel it come out of there. Heat doesn't come through those vents on normal heater setting those are the defroster vents.

Defroster not blowing


your blend door motor IS your defroster problem , as it is needed to direct heat mixed with the ac to properly defrost the windshield . if when you change your blend door motor and the problem still exsist , then youy have a defective blend door package , meaning one of the doors are faulty , which could get very expensive to repair , good luck !!!

Dash defogger does NOT blow on windshield. It blows thru dash only, regardless of setting (dash only, dash & feet, feet only, defroster only, defroster & feet, etc) Help?


this could be a simple switch problem, if it is a rotary switch, pull the front of it off and try turning the little knob with pliers, the cheap plastic used now sometimes rounds off if this isnt problem depending on type of switch electrical connections on switch could be bad or vaccum could be plugged or non existant

When put my selector to windshield my ac turning on automatically


are you referring to the windshield defroster? if so, then it is normal for the ac compressor to cycle on and off, the reason being that, during winter months, is helpful for the proper function of the ac compressor to cycle on and off so as to not lock up.
