99 F150 SCAB Blend Door Actuator/Motor
For the life of me, I cannot find a thread that I saw about 6 months ago. I'm looking for a pictorial view of exactly where the blend door actuator/motor is or what it even looks like. I have removed the black cover that is just over the tranny hump and I'm not seeing the motor, housing, or the linkage that I'm supposed to see moving according to other threads. Any help is appreciated as this is the first step in my diagnosis of probably having to replace the blend door...the dreaded dash removal.

The motor is just above the black duct pipe on top of the hump. Its a real bitch to remove unless you cut the duct pipe. Reason being one of the screws that holds the duct pipe is hidden up above the gas peddle and untouchable!!
I think three screws hold it in. If you hear clicking when turning the control **** to its limits the motor works but the door is bust. You can also touch the motor shaft and feel if it moves.
I ended up replacing both. The door breaks because it heat hardens and the motor trys to move it too far. Not a bad job to replace but takes a day to do.

That looks like it. And as you can see its not easy to get to. The motor is inside that white box and its small. drives a few gears to the shaft to move the blend door. Your set up is a little different to mine but still looks tough to change.
You need to be able to drop that white box down to remove it.

Ease back the carpet and remove the black bar on the right. Feel around for bolts or screws holding up the duct. On mine I found one at the rear behind the actuator with noway of getting to it. 11 year old truck? what the hell, cut the pipe/duct, its hidden so some black duct tape will fix it.
If not I would have had to take apart most of the truck to get to it!!
That shaft is about an inch longer than you can see at the moment!!
