AC blows air from defroster
chec for a vacuum leak hose off/broken...
I'm sorry. I gave the wrong year for my car. It's a 2002 gmc yukon SLE 2 wheel drive. Thank you so much for your quick answer. Could you try again? Again, the AC air comes through the defroster vent. My husband says there are no vacuum hoses for this model. says it runs by several motors. I have no idea if this is correct. Help!
