When it comes to classic cars, the 1967 Chevrolet is still one of the most popular models to this day. This iconic car has been the subject of many restoration projects, and one part of the restoration process that enthusiasts often struggle with is the wiring diagram for the wiper motor.
What is a Wiper Motor?
A wiper motor is a key component of a car’s windshield wipers. It is responsible for powering the wiper blades across the windshield, helping to clear it of rain, snow, and other debris. In the 1967 Chevrolet, the wiper motor is located under the hood on the passenger side of the car.
How Does a Wiper Motor Work?
The wiper motor is powered by electricity from the car’s battery. When the driver activates the wiper switch, the electrical current flows through the wiring harness and into the wiper motor. The motor then converts the electrical energy into mechanical energy, which powers the wiper arms and blades in a back-and-forth motion.
Why is a Wiring Diagram Important?
Restoring a classic car like the 1967 Chevrolet can be a challenging process, particularly when it comes to the wiring. This is where a wiring diagram becomes essential. A wiring diagram is a visual representation of the electrical system in a car. It shows how each component is connected and where the wires run.
Having a wiring diagram for the wiper motor ensures that you can wire it up correctly, with all the connections and wires in the right place. This will prevent any potential electrical issues and ensure that your wiper motor works as it should.
The 1967 Chevrolet Wiper Motor Wiring Diagram
The wiring diagram for the 1967 Chevrolet wiper motor is a relatively straightforward one. It features just four wires, which are color-coded to help identify them:
| Wire Color | Function |
|---|---|
| Dark Blue | Wiper Motor High Speed |
| Light Blue | Wiper Motor Low Speed |
| Black | Ground |
| Yellow | Power |
It’s important to note that this wiring diagram is for the 1967 Chevrolet with a two-speed wiper motor. If your car has a single-speed wiper motor, the wiring diagram will be slightly different.
Wiring the Wiper Motor
To wire up the wiper motor on your 1967 Chevrolet, you will need to follow these steps:
- Identify the four wires on the wiper motor: dark blue, light blue, black, and yellow.
- Connect the dark blue wire to the high-speed terminal on the wiper motor.
- Connect the light blue wire to the low-speed terminal on the wiper motor.
- Connect the black wire to a ground point on the car’s chassis.
- Connect the yellow wire to a source of power, such as the car’s battery.
Once you have wired up the motor, you should test it to ensure that it is working correctly. Turn on the wiper switch and observe the wiper arms to check that they are moving across the windshield at the correct speed.
