ISSUE
Some 2003-2005 Expedition/Navigator vehicles built before 4/1/2005 may exhibit an inoperative rear window wiper, where the rear wiper motor can be
heard operating, but the rear wiper arm is not moving. This condition may be due to the rear window wiper motor mounting surface not being
perpendicular to the liftgate door, resulting in the rear wiper arm pivot disengaging from the wiper motor.
ACTION
Add a shim between the wiper motor bracket and wiper motor mounting surface at the two (2) bracket holes closest to the front of the vehicle.
SERVICE PROCEDURE
1.
Access the rear wiper motor bracket by removing the liftgate trim panel per Workshop Manual Section 501-05.
2.
Remove the two (2) wiper motor bracket bolts closest to the front of vehicle (Figure 1) and loosen the other two (2) bracket bolts. Add a
0.04-0.08(1-2 mm) thick stainless steel washer between the wiper motor bracket and mounting surface, to raise the rear of the wiper motor
assembly.
3.
Reinstall bolts and torque to 97 lb-in (11 N.m).
4.
Verify that the pivot shaft pin is aligned with the hole in the motor disc. If not, add or remove washers as needed to obtain alignment.
5.
Install liftgate trim panel per Workshop Manual Section 501-05.
