Service Procedure
Service ProcedureContents of Service Kit
Replacement Kit P/N 20785184: Link is assembled with the motor crank arm.
Tools Required
1. Remove the wiper arms. Refer to Windshield Wiper Arm Replacement in SI.
2. Remove the air inlet grille panel. Refer to Air Inlet Grille Panel Replacement in SI.
Notice:
Before removing the wiper system module from the vehicle, make sure that the module was parked. All the operations on the wiper system module must be done on a clean environment, free from metal particles or any kind of dirt to avoid contamination of the grease in the plastic sockets.
3. Remove the windshield wiper motor/transmission assembly from the plenum panel of the vehicle. Refer to Windshield Wiper Motor and Windshield Wiper Transmission Replacement in SI.
4. Place the windshield wiper transmission assembly on a work bench.
5. Using the J 39232, Wiper Linkage Separator or an equivalent tool, detach the links from the motor crank arm. Remove the closed plastic socket first and then followed by the open plastic socket.
6. After removal of the closed socket of the passenger-side (PS) link, check for any crack or damages. If cracks or any deformation are present on the socket, the entire wiper system module must be replaced.
7. Remove the closed socket on the driver-side lever. Discard the link.
8. Using a light colored permanent fine-line marker, make a continuous line that goes from the middle of the shaft until the motor bracket. This will be used to determine if the motor shaft moves out of park during crank replacement and nut installation.
9. Uninstall the motor crank arm nut using a ratchet and 13 mm socket. Hold the motor crank arm with a wrench or channel lock to prevent the motor shaft from turning while removing the nut. Discard the nut.

10. Remove the motor crank arm with J 39822, Wiper Arm Puller or an equivalent tool. Make sure not to damage the water cap (white plastic). Any crack or deformation on the water cap is not allowed. If this is damaged, a new motor must be used. Discard the motor crank arm.
11. Clean the motor shaft splines (1) with a wire brush to remove any residue. If there is any glue or epoxy residue on the shaft thread, remove as much material as possible. Do NOT use any chemical or cleaning agent, or any tool other than a manual wire brush.
Shaft Conditions
(1) Good Motor Shaft. Sharp splines with no damage or dirt between teeth. Re-use wiper motor. (2, 3 and 4) Damaged Motor Shaft Splines. Broken, cracked, rounded or worn teeth. Discard wiper motor.
12. After cleaning the motor shaft, check the physical characteristics of the shaft splines (teeth) and thread. Both should be clean and free from any damage or deformations. If deformations are present, the motor is to be discarded and a new one is to be used.
13. Prior to re-assembly of the wiper module, check for any contamination or dirt on the sockets. Make sure that the grease is clean and present on all the sockets and ball studs.
14. Using J 39529, Wiper Linkage Installer or an equivalent tool, attach the closed socket of the driver-side link to the driver-side lever (driver-side open socket link already attached with service kit).
15. Loosely attach the motor crank arm to the motor.
Important:
Ensure that the link and motor crank arm are straight. Use the edges of the link and crank arm to confirm if both parts line up straight.
16. Align both the motor crank arm and the link with the open socket so that both parts are in a straight line.
17. Hold the motor crank arm with a wrench or channel lock to prevent the motor shaft from turning while tightening the nut. Ensure that the new flange nut with epoxy (included in the kit) is used.
18. Tighten the motor crank arm nut to 25 Nm-26 Nm (18.4 lb ft - 19.2 lb ft).
19. After tightening the nut to the shaft, check and confirm if the original markings to the shaft and bracket still line-up.
20. Using J 39529 or an equivalent tool, attach the second transmission arm (closed socket type) to the motor crank arm.
21. After this assembly procedure, the motor crank arm and the links should be aligned.
22. After completion of assembling the wiper module, bring the wiper module to the vehicle and run the wiper system for a few cycles. After cycling, bring the wiper module to park.
23. Install the wiper motor/transmission assembly into the vehicle. Refer to Windshield Wiper Motor and Windshield Wiper Transmission Replacement in SI.
24. Install the windshield wiper arms and blades. Refer to Windshield Wiper Arm Replacement in SI.
25. Cycle the wiper system to verify the park position. The correct parking position can be verified by checking that the wiper arms move initially in the up-wipe direction. If the movement starts in the down-wipe direction and then changes to the up-down direction, the wiper linkage assembly may be installed incorrectly.
