My passenger side blows cold; my driver's side is still hot and not controllable. Where is the driver's side blend door actuator located? I've already found the passenger side.

The left side actuator is mounted on the underside of the HVAC. Remove the trim cover and you will see it. You may need to remove the center console to get to the actuator.

It looks harder than it is. I have done it without pulling the center console but it's a tight fit. The cover is just a flimsy item that hides the molded plastic of the case (and provides a great place for dirt to hide) The actuator is just the screws and electrical plug.
