Ok late last August I had my air conditioner fixed, replaced compressor, etc. Used it a couple of times and worked fine. Drove the car this winter and the heater never seemed to work. Now that it's hot again I wanted to use the A/C but all I get is hot air! and yes I checked the freon level it shows full charge. any ideas?

First and most important question, is the compressor cycling?

Hello gbickham,

i think the compressor has a fuse. Did you check fuses?
Does the AC compressor kick in when you activate the AC?

Thanks for the tips Ill check as soon as it stops raining! Haha

Several months ago, back in winter, I noticed that my heater was not producing very hot air. After some research I found a thread about the door inside the HVAC box that directs air toward or away from the heater core. I removed the door from inside the box and found that the door is actually made from thin sheet metal filled with large holes and the entire door covered in foam. The foam dried out and flaked off exposing the holes. The door could not separate cold air from hot air. I covered the door in thermal tape and reinstalled. Heat and air work fine.
