I'm driving with my AC on all is fine then it randomly turns to the heater. If I stop and turn the car on and off it fixes for a while then randomly goes back to heat. Why?
I am driving with my AC on all is fine then randomly it turns to the heater. If I stop and turn the engine on and off it goes back to AC. Why does this happen? My mechanic tells me I was low on Frion? but it happens even after that? Why?
