• Q: How to replace the wiper motor on 2005 Cadillac DeVille?

  A: Use both the Wiper Transmission Separator part number J 39232 and Wiper Transmission Installer part number J 39529 to replace the motor. Begin your work by taking off both wiper arms and the air inlet grille panel. Unscrew the three bolts and two nuts keeping the windshield frame reinforcement in place before extracting the reinforcement part. Turn the wiper motor crank arm to its alternate area and extract the wire grommet from the plenum opening. Disconnect the wiper motor electrical connector while pushing its wires and grommet through the plenum opening. Unscrew the three screws of the wiper system drive module and lift it from the vehicle. The Wiper Transmission Separator tool (J 39232) helps detach the drive link from the wiper motor crank arm before you unscrew and remove the wiper motor from the drive system module. Fasten the wiper motor to the wiper drive system module by screwing it in until reaching 8 N.m (71 lb in) resistance. Set the wiper drive link into the wiper motor crank arm using J 39529, place the wiper module downward into the upper plenum, and turn the unit to display the motor nose area toward the vehicle's rear. Fasten three screws to secure the wiper drive system module and tighten them to 8 N.m (71 lb in). Insert the wire bundle with grommet through the plenum opening and connect the motor harness. Afterward, mount the grommet back into the plenum hole. Use the three bolts and two nuts to reattach the windshield frame reinforcement and tighten them to 9 Newton meters while putting back the air inlet grille panel and wiper arms. Test the wiper operation to verify correct performance.
