The driver's side A/C blows cool, and the passenger side blows warm air. I’m going to attribute it to a blend door actuator. I’ve watched a bunch of videos and noticed different locations of this part. Can someone confirm if the actuator is just under the glove box where I’d remove the kick plate? Or is it deep behind the dash where I’d have to remove the whole dash? TIA

Hello,
The passenger side blend door actuator is located on the side of the HVAC box.
In order to replace the passenger side blend door actuator, you will have to remove the dash.

I have attached the replacement procedure below, including the reprogramming steps for the replacement actuator.

Let me know of any questions.
Thank you.
