'97 Blazer seems to be stuck on the defrost setting all the time. Air blows out the top vent primarily, with a small amount coming out at the floor. When starting up on cold mornings, it feels like the AC blows for a brief time, which I was told is how the defrosted removes condensation off the windshield. Once the truck is warmed up, fan speed and temperature selector all work as expected, I simply cannot change where the air is blowing out from.
Any suggestions on where to start looking? Any fuses or vacuum lines I should be aware of?
