It is a door actuator motor that is not working,the dash will have to be removed to replace the actuator motor.

SOURCE: heat works on driver side, passenger side blows cold air.

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

2003 Mitsubishi Eclipse Spyder, can't figure out why the heater blows cold air on the drivers side and warm air on the passenger side? A/C works great. I have flushed the heater core and it seems to flow...


There are a couple of possibilites. 1 Is your vehicle equipped with seperate climate controls for the driver and passenger, if so your warm/cold air motor door on the drivers side is malfunctioning. This is located under the dash.2 Your climate controls on your dash are not working properly. Hope this helps.


Please take a moment and rate my answer..........Thanks

1995 Lesabre blows hot on drivers side, cold on passenger side


THIS IS A GUESS. Both sides probabley have "mix" dampers that regulate temp by mixing hot and cold air to make you comfortable. Passenger side must not work properly, stepper motor? Dirty actuator? Temp sensor on passenger not working? Don't honestly know but I'm not sure a do it yourselfer could figure it out. Sounds complicated.

Heater on driver side blows cold air


something wrong with flap operating device ?? would need to get my head under the dash to sort it though because their is so many variables of what could be causing it ,quick fix is to disconnect the operating mechanism and put a elastic band on it till the weather warms up
