ISSUE
Some 2003-2007 Expedition and Navigator vehicles, the rear wiper may not return to park position. In this case, the rear wiper system will attempt to park periodically causing a battery drain.This concern may be caused by corrosion on the wiper pivot shaft assembly.
ACTION
Use the following Service Procedure to identify and replace the rear window striker/wiper pivot shaft assembly.
SERVICE PROCEDURE
1. Disengage rear wiper mechanism by partially opening the rear liftgate glass. (Figure 1)
2. Access the rear wiper arm attaching nut. (Figure 2)
3. Use a torque wrench to measure the amount of torque necessary to rotate the wiper arm throughout the entire travel of the wiper arm. (Figure 3)
a. This must be done while the glass is open so that the wiper mechanism is disengaged from the motor drive plate.
b. The wiper blade should be in full contact with the glass throughout the entire stroke of the arm.
c. The measurement taken must not exceed 49 lb-in (5.5 N.m) of force when rotated in either direction.
(1) If the force is greater than 49 lb-in (5.5 N.m), then replace the rear window striker / wiper pivot shaft assembly. Refer to Workshop Manual, Section 501-16 - Wipers and Washers Removal and Installation. (Figure 4)
(2) If the rear window striker/wiper pivot shaft assembly is within specification, then follow normal Workshop Manual diagnostics.
