• Q: How to replace the wiper motor on 2003 Cadillac DeVille?

  A: Begin replacing the wiper motor by obtaining the needed tools Wiper Transmission Separator (J39232) and Wiper Transmission Installer (J39529). The replacement starts with taking off wiper arms and the air inlet grille panel. First unlatch the three bolts and two nuts holding the windshield frame reinforcement in place before you remove the reinforcement assembled part. Move the wiper motor crank arm from its park position to the other extreme then unscrew the grommet from its plenum hole location before unplugging the wiper motor connector. Push the harness and grommet into the plenum hole before you take out the wiper system drive module with its three screws. Use Wiper Transmission Separator J 39232 to disconnect the wiper motor crank arm drive link before removing the motor securing screws and removing the motor from the wiper drive system module. You should fasten the wiper motor to the wiper drive system module with screws and tighten them to 8 N.m (71 lb in). First thread the drive link onto the wiper motor crank arm using the Wiper Transmission Installer J 39529. To install the wiper module into the upper plenum, position the motor nose at the bottom facing backward. Secure the wiper system module properly using three screws as you tighten them to 8 N.m (71 lb in). Push both motor wires through their defined plenum entry point and then reconnect the motor wires at their attachment point. Attach the protection cover to the plenum hole opening. Reattach the windshield frame reinforcement parts by three bolts and two nuts at 9 N.m torque (80 lb in) before adding the air inlet grille panel and wiper arms. Test the wipers by activation to check if they work properly.
