I was driving to town yesterday evening and turned the AC on. after about 30 seconds i became worried because the air was warm and it was pretty cool outside. i told my wife that i thought my AC was not working but she said it was. Her two vents were nice and chilly but mine had the heater on!?!?!? how does that work?

on the drive back it did not do it, but i still want to know what i need to check out. any suggestions?
