replace bender door for ac and heat

you are talking about the blend door motor. remove the radio and take the lower case below the center of the dash. it is a rectangular box attached by 3 small bolts and an electrical connector. it pays 1.5 hours in a shop and the motor is about 99. Roy

On the Fords that I have done, you have to empty the A/C system , remove the dash and then remove the entire heater plenum to access the actual blend door. It is a pretty huge job that takes about 9 hours or more. Generally you can find another blend door at a junk yard, or sometimes at the dealerships. The gears on the shaft on the blend door, that are driven by the blend door actuator, are what become stripped.
