Hi!
My driver's side blend door has been stuck on heat for some time. Once the truck is warmed up, there is hot air constantly weeping from the driver's side vents, even when the blower is off. The passenger side seems unaffected.

Where is the actuator physically located in the vehicle? I'd like to replace it myself, but my Haynes manual is useless in this regard.

Thank you for your help.

Hi:

I need to know if you have automatic climate control or manual.

Regardless of which you have, this isn't an easy one. If you look below, I have attached a picture of its location along with the directions for replacing it. Note that the component is under the dash. On this vehicle, it appears a good bit needs to be removed to access it.

I am providing the basic directions for the automatic climate control. If you have something different, I need to know. Once I get that info, I can provide more detailed directions.

Let me know.

Joe

See pics below. Pic 3 indicates ATC. That is automatic temp control. Pic 4 is for manual. Note the things highlighted in blue. Those are the directions for accessing it. I will provide that once we confirm the system you have.

Hi Joe,

Thanks so much for the reply. I have automatic climate control. I should have included that detail when I posted the question. I've added an image of the controls to confirm.

It is the driver's side that is affected, not the passenger side. Heat always on the driver's side.
