vacum

  1. Heating & Cooling
    When I have either heat or a/c and the blower is on face or floor, and then I take off it will go to the defrost and when I am not in overdrive it will return back to where it was. Since this happened I also noticed my cruise control is not working. Is this a vacum issue? Where do I start? 1999...
