Condition
Some customers may comment that the rear wiper jumps when the fog lamps are turned on.
Cause
Electrical feedback from the fog lamp circuit into the ground of the rear window washer pump may cause this condition.
Correction
To perform this correction, you will need to obtain the following items:
^ A J 38125-B Terminal Repair Kit. Obtain the following parts from the kit.
- P/N 12041351 (Cable Seal) from tray # 2
- P/N 12077411 (Terminal) from tray # 2
- P/N 12103507 (Ring Terminal) from tray # 18
^ A 508 mm (20 in) length of Black, 0.5 mm (20 gauge) or 0.8 mm (18 gauge) wire
Important: Do not re-use the old cable seals. Replace old cable seals with P/N 12041351.
Isolate the rear washer pump ground circuit by performing the following steps.
1. Remove the left side fender to radiator tie bar diagonal brace.
2. Remove the battery.
3. Remove the battery tray.
4. Remove the bolt that secures the washer bottle to the upper radiator tie bar.
5. Raise the vehicle on a hoist.
6. Remove the lower washer bottle mounting bolt.
7. Locate the rear washer pump motor, mounted into the washer solvent bottle under the hood, and disconnect the wiring connector for the rear washer pump (Dark Green/White stripe and Black wires).
8. Remove the black wire from the connector. Cut the wire and tape the end to seal out moisture intrusion. A non-sealed wire will allow moisture to wick up the strands of the wire and may corrode other components/connections.
9. Slide one end of the new wire through the weather pack seal that was removed from the old wire.
10. Properly attach the 12077411 terminal (crimp and solder) to one end of the new black wire.
11. Properly attach a 12103507 ring terminal (crimp and solder) to the other end of the new black wire.
12. Place the new terminal and wire assembly into the rear washer pump connector and properly position the weather pack seal.
13. Reconnect the connector to the rear washer pump.
14. Route the new black wire down to the attaching point on the frame, same location as the battery ground. Follow the battery cable routing.
15. Remove the ground to frame attaching bolt.
16. Clean the battery cable and G100 ring terminals of contamination.
17. Install the new wire ring terminal between the battery ground wire (5) and the existing G100 ground wire (3).
