Dorman Heater Blend Door on 1999 Lincoln Navigator

Where is the Dorman Heater Blend Door located?

Asked by for the 1999 Lincoln Navigator
All the air blend doors are located on the side of the heating and air conditioning evaporator box behind the dash. The Ford NGS scan tool can be used to retrieve trouble codes from the heating and air conditioning system. The actuators that work the blend doors are operated by vacuum hoses ensure none of the hoses have become knocked off the actuators.
For better instructions there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual.
