Wiper Motor

To service and repair the wiper motor, be ready with the tools: Wiper Transmission Separator (J 39232) and Wiper Transmission Installer (J 39529). First, walk to the wiper arms and the air inlet grille panel but remove them first. Then, get all the three bolts and two nuts fastening the windshield frame reinforcement, and you can also apply the root of the windshield frame reinforcement. Rotate the wiper motor crank arm of the park position to the opp or the other side and then remove the wiper motor harness grommet from plenum hole and then disconnect the wiper motor harness and connector. Push the harness and grommet through the plenum hole then take out the three screws securing the wiper system drive module and remove the module from the vehicle. Separate the drive link from the wiper motor crank arm with the help of Wiper Transmission Separator (J 39232); remove the screws that hold the wiper motor in before removing it from the wiper drive system module. For the installation, the wiper motor should be mounted on the wiper drive system module and use the screws to fasten it to the 8 N.m (71 lb in). Mount the drive link to the wiper motor crank arm using the Wiper Transmission Installer (J 39529) and then load down the wiper module down in the upper plenum with the nose of the motor oriented downward. Twist the module to position the motor nose toward the back end of the car and fix thewiper drive system module with three screws and tighten it to 8 NM (71 lb in). Push the harness and grommet into the plenum hole, reattach the wiper motor harness connector, and install the harness grommet to the plenum hole. Finally, reinstall the windshield frame reinforcement bolts and nuts into 9 N.m (80 lb in) before air inlet grille panel and wiper arms. Run the wipers in order to test the proper functioning.

The tool requirements for wiper motor replacement include the The repair requires utilization of Wiper Linkage Separator (J 39232) and Wiper Linkage Installer (J 39529). Wiper Linkage Separator (J 39232) and Wiper Linkage Installer (J 39529). Start the process by taking off the wiper arms together with the air inlet grille panel. Start by taking out the three bolts and two nuts which keep the windshield frame reinforced together followed by extracting the windshield frame reinforcement from its place. The wiper motor crank arm should be rotated to the opposite area from park position before extracting the harness grommet from the plenum hole and disconnecting the wiper motor harness connector. You should move the harness along with grommet through the plenum hole while you remove the three screws which retain the wiper system drive module until you can extract it from the vehicle. To remove the wiper motor from the wiper drive system module users should first separate the drive link from the wiper motor crank arm by using Wiper Linkage Separator (J 39232) and then remove all the screws that secure the wiper motor. Screws should be tightened to 8 N.m (71 lb in) for attaching the wiper motor to the wiper drive system module. Install the drive link onto the wiper motor crank arm by using the Wiper Linkage Installer (J 39529) then guide the wiper module into the upper plenum with the motor nose facing downward before rotating the module to face towards the back of the vehicle. Secure the wiper drive system module using three screws that need a torque setting of 8 N.m (71 lb in). Reconnect the wiper motor harness connector while installing the harness grommet through the plenum hole. The procedure ends with the installation of the windshield frame reinforcement using three bolts and two nuts and torque adjustments to 9 N.m (80 lb in). Next, install the air inlet grille panel and wiper arms. Test the wipers to confirm they work correctly.

Rotate the wiper motor crank arm from the park position to the opposite area and remove the harness grommet from the plenum hole.
