• Q: How to replace the wiper motor on 2001 Chevrolet Impala?

  A: Start repairing the wiper motor by taking the wiper arms off with the air inlet grille panel. Disconnect the wiper transmission and then remove the power connection for the wiper motor using the wiper transmission separator (J 39232). Use an appropriate tool to loosen three screws then take the wiper drive system out. The next step is to separate the rubber boot from the wiper motor crank arm. Securely push a soft mallet against a screw of the wiper motor even as you raise the crank arm until the screw loosens then extract it along with the crank arm. You must disconnect the wiper motor first from its wiper drive system module by taking out three screws. Then remove the shaft seal and water shield from the wiper motor unit. Place the water shield first then add the shaft seal on the wiper motor unit for proper installation. Secure the wiper motor onto its assembly using three screws and tighten them to 7 N.m (62 pounds of torque). Slide on the motor connector then start the ignition while selecting delay on the switch. Change the ignition to off after the wiper motor stops at its interior wipe position and extract the electrical connector again. Fasten the wiper motor crank arm to the wiper motor so its bracket tab has a 4-8 mm space to the lower arm and torque the retaining screw to 16 N.m pressure. Hold the rubber boot onto the wiper motor crank arm before mounting the wiper drive system module back to the vehicle with three screws at 10 N.m (88 lb in). Put the wiper transmission installer (J 39529) device on the wiper motor crank arm to link components properly. After that plug the wiper motor electrical connection back in, install the air inlet grille panel, wiper arms, and test the windshield wipers.
