Hot or Cold, No Warm
I've a '99 F-150 and the temp control usually will not come off of hot. There are a times when I can get it to blow cold air, but if I let the rpms drop below idle speed or if I hit a bump or no reason, I hear the blend door shut (or open) and the hot air comes rolling in. I have to turn the heat/A/C switch to the off possition and leave it off for a while before I will even have a chance a reclaiming cool air again. Anybody have any ideas on whats wrong or how to fix it?
