How to Repair a 1987 Buick Regal Windshield Washer Motor

The wiper motor is easy to remove.

The windshield wipers on your 1987 Buick Regal are powered by a motor that also pumps wiper fluid. If your windshield wipers are not working, first check the fuse in your vehicle's fuse box to be sure that it is working properly. If the fuse is still working, you can assume that the wiper motor needs to replaced. This replacement procedure is easy enough that you can perform it yourself without needing to hire a mechanic.

Things You'll Need

• Drain pan
• Ratchet and socket

Instructions

1. Locate both the wiper motor beneath the hood on the firewall and the wiring harness just below the wiper motor.

2. Disconnect the wiring harness from the electrical connector.

3. Disconnect the individual electrical connections by lifting the connecting tab for each connection and pulling each one from the connector with your hands.

4. Place a drain pan just beneath the washer hoses to catch the wiper fluid when you remove the hoses.

5. Detach the two washer hoses with your hands. Be sure to properly label them for easy reinstallation.

6. Remove the three bolts that connect the wiper motor to the firewall using a ratchet and socket.

7. Pull the wiper motor free from the firewall with your hands.

8. Install the new wiper motor and follow the previous steps in reverse to complete the installation.

9. Refill the wiper fluid tank.
