Why does drivers side blow hot air when a / C is turned on?
Why does drivers side blow hot air when a / C is turned on? Re: Drivers Side blows hot air when a/c is turned on.. Climate control system was not responding correctly. Blowing hot on driver and cold on passenger, from dash and floor only. Dual temperature would not respond to adjustment, and vent knob would not change direction of air flow from dash to floor or defrost. What should I do if my HVAC actuator is not working? If you feel or hear the actuator clicking, or the HVAC arms are not moving, the actuator is probably at fault...
