No heat on drivers side
I have a 2008 Lincoln Navigator that has no heat flowing to the drivers side
of the car. The heat works in the passenger side and the rear of the vehicle.
The fan speed changes when I increase and decrease it. Also I am able to
manual change the air flow from the windshield, vents, and floor.
With the information I have read I suspect it to be the blend door actuator
though I am not sure how to trouble shoot this fully. Please advise.
