Hi all,
My 1991 Cavalier only blows air through the dash vents. This is a problem since I live near Chicago and really need the windshield defroster to help clear the windshield.
I thought perhaps a cable broke, but I doubt it now as the tension on the lever seems to be the same as before when switching the output from heater(feet) to vent(face) to defroster(upper dash to heat the windshield). No matter which setting I select, it only blows the hot air through the dash vents which point at the driver's face.
Is this a vacuum issue somewhere? If so, where?
What should I check to see if I can solve this problem?
