Hi,

Possible electrical issue with blend door. I changed out the actuator and still it doesn't move, the one which is located at the drivers gas pedal. Temperature changes fine and the rear A/C blows cold too. Is there a fuse for this specific actuator or what else could it be?
Do you
have the same problem?

I believe the one you changed was the blend door actuator for the driver side. The blend door is what controls the mixture of warm and cool air to get the temperature correct.

The mode door is what you need to change as this is what controls where the air comes out.

I attached the info for this actuator. Let me know if you have any other questions and what you find. Thanks

Hi,

You indicated you replaced the actuator but the title is related to the blend door. The actuator that controls the air flow direction is the mode door. I attached a pic of its location. Is this the component you replaced? The mode door actuator is behind the dash on the passenger side. Here are the directions for removal and replacement. The attached pics correlate with the directions.
