Wiper Motor Wiring Diagram

Introduction

A wiper motor is an electric motor that drives the windshield wipers of a vehicle. The wiper motor is typically mounted on the firewall under the dashboard. It is connected to the windshield wiper transmission, which is responsible for moving the wiper blades back and forth across the windshield.

Wiring Diagram

The wiring diagram for a wiper motor will vary depending on the make and model of the vehicle. However, most wiper motors will have the following basic connections:

Power: The power connection is typically a red wire that is connected to the positive terminal of the battery.

Ground: The ground connection is typically a black wire that is connected to the negative terminal of the battery.

Control: The control connection is typically a blue or green wire that is connected to the wiper switch.

Operation

When the wiper switch is turned on, it sends a signal to the wiper motor. The wiper motor then uses the power connection to draw current from the battery. The current flows through the motor and causes it to rotate. The rotation of the motor is then transferred to the wiper transmission, which causes the wiper blades to move back and forth across the windshield.

Troubleshooting

If your windshield wipers are not working, there are a few things you can check:

Check the power connection: Make sure that the power connection to the wiper motor is secure.

Check the ground connection: Make sure that the ground connection to the wiper motor is secure.

Check the control connection: Make sure that the control connection to the wiper motor is secure.

Check the wiper motor: If the power connection, ground connection, and control connection are all secure, then the wiper motor may be faulty.

Replacement

If the wiper motor is faulty, it will need to be replaced. The replacement process will vary depending on the make and model of the vehicle. However, most wiper motors can be replaced in a few hours.

Conclusion

The wiper motor is an important component of your vehicle's safety system. By understanding how the wiper motor works and how to troubleshoot it, you can help keep your windshield wipers in good working condition.
