My airconditioning comes on as well as the heater. No matter which area the dial is the ac comes on. the the heat comes on for a few seconds then the ac cool air over powers it. I noticed there was something going on a few months age but if I turned the dial a few off and on past the ac settings the heat eventually worked with out the ac kicking on. What is wrong? Has any one had a problem like this before?
