Principles of Operation
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The exterior mirror control switch is located on the LH door trim panel. Adjusting the exterior rear view mirror control switch to the LH or RH position determines which exterior mirror will be controlled. Power is supplied to the exterior mirror switch from the central junction box (CJB).
The exterior mirrors use a jumper harness between the vehicle wire harness connector and the exterior mirror motor. The exterior mirror jumper harness is integral to the exterior mirror. If a concern with the exterior mirror jumper harness exists and cannot be repaired, a new exterior mirror must be installed.
