I have no heater on my drivers side (dual control). The air flow is not as greate as on the passenger side. I can see the actuator rotating 95 degrees when I move the climate control lever. I manual operated the door and it swings fine, and does not correct my problem. Not knowing the internal ducting on this car is not helping. Any suggestions.

Thanks

With dual climate control, you have two blend air doors. Since you are getting heat on one side of the vehicle, that tells me the heater core is fine. However, it sounds like one of the blend air doors isn't functioning and allowing heat to enter the vehicle. The blend air doors are located near the heater core in the heater box. Check that to see if one isn't working.

The driver side door is functioning (actuator works and door is free to swing. I assume that this is the blend door you are referring to.

I'm not sure if it what I am referring to. There is only one heater core, so if you have heat on the passenger side and not on the driver's side, that tells me the door I am referring to isn't opening. If it was, you would get heat. Which door are you referring to?

I replace the door swing actuator and that fixed my problem. Took me 4 hours to get it out and 45 minutes to install it. Thanks

Glad you got it fixed. I had a feeling that was the problem.

Let us know if you have questions in the future.
