2000 Cable potentiometer to blend door
Our 2000 4X4 is blowing colder air than the Montana winds in winter! I have replaced the cable potentiometer (CABLE)...
when I connect it to the actuator for the blend door.....nothing will move! I have read and watched every article I could find
but none of them pertain to this CABLE style control. I need some help. The Ford PN YL5Z19988AA. The Dealer had a tough time with all the supercedures but he got me one!

Welcome to the forum
Your Ranger blend door may not be same as our full electric version
But your problem with no blend door movement may be broken door not the actuator, whether cable operated or electric
Blend door failure is fairly common on Fords since they went to electric versions in 1995
Did you try to move the blend door manually before installing the motor/actuator on it?
The actuator, on top of heater duct is the most common thing to fail, but the pivot that the actuator moves can break as well, and its part of the Blend Door
Watch this video: youtube.com/watch?v=ytSaN7l2xBs
You can do this to check blend door movement but also to get HEAT back in the cab, NOW
It doesn't hurt anything, easily covered over with duct tape or similar
The Blend door ROUTES air either around the heater core or thru the heater core, or in between, some thru core some around core :)
To access or change the blend door you must remove the whole dash assembly from the firewall
Heater core???
After engine is warmed up are BOTH heater hoses HOT, they should be, if not then heater core is plugged up, not a blend door issue at all
