heater & a/c switch from vent to defroster
I have a 1996 Blazer and whenever I accelerate hard like going uphill or passing someone my a/c or heater, whichever I have on, switches from blowing out of the vents and starts blowing out the defroster. More of an aggravation than a real problem but I know its not suppose to be doing that. Vaccuum issue? Thanks in advance
