My a/c would blow hot air at times so I replace the blend door actuator but this morning had the heat/defrost on and was working fine then the heat went away ? I tried to a just the temperature but no luck. I did turn my truck off and restarted and the heat started working again. Any pointers ? My a/c seems to be working fine. And the blower is working fine.
