Re: AC blowing warm air

Easiest way to prove/disprove a temp door issue is to eliminate the source of the heat, by pinching off the heater hose temporarily. If no hot water, no heat, if air temp returns to cool air, then the temp door is stuck in heat position. Then you have to go under dash and see if actuator is working, or there is a broken temp door axle.
