If you are working on the wiring of your vehicle’s rear wiper motor, it is important to have a clear understanding of the wiring diagram. With a proper understanding of the wiring diagram, you can ensure that the wiring is set up correctly and the wiper motor will function properly.
What is a Rear Wiper Motor?
A rear wiper motor is a device that is responsible for powering the rear windshield wiper on a vehicle. The motor is typically located in the rear hatch or trunk area of the vehicle and connects to the wiper arm and blade through a small linkage assembly.
How does a Rear Wiper Motor Work?
When the driver activates the rear windshield wiper, an electrical current is sent to the wiper motor. The motor then uses the current to power a small electric motor that turns a camshaft. The camshaft moves a linkage assembly, which in turn moves the wiper arm and blade back and forth across the rear windshield.
What are the Components of a Rear Wiper Motor Wiring Diagram?
A typical rear wiper motor wiring diagram will include several components, including:
| Component | Description |
|---|---|
| Battery | A source of electrical power for the wiper motor |
| Fuse | A protective device that limits the current flowing through the wiper motor circuit |
| Switch | A device that allows the driver to control the operation of the wiper motor |
| Wiper Motor | The electric motor that powers the wiper arm and blade |
| Linkage Assembly | The mechanism that connects the wiper motor to the wiper arm and blade |
