when i use my heater or air and set the controles to floor or dash, or A/C after about 2000 RPM's and im pulling away from a light the air starts to come from the defrost vents and stops coming from the dash or floor. this has been going on for about 2 years and is geting worse. it used to start doing it after about 45 now it is about the same time my foot goes on the gas pedel. help its geting hot and i want my air to work!!! thanks.

 

SEACRH for any of the dozens of previous posts that contain both words "defrost" and "vacuum".........

Dang, why doesn't this site use stickies or an FAQ??????
