So past few days my HVAC on my 03 GT has been getting screwy. When I have it on cold it blows hot unles I jiggle the swtiches then it go right. Now even when the slider is all the way up I get luke warm as best heat. Unles It seems like the driver side vents are not blowing but the passenger is blow good and strong. If I flick it all the way to cold the dirver side will start blowing again. Is the control unit its self going bad? This is a manuel climit duel zone car for the record.
