When it comes to restoring a classic car, having a wiring diagram is essential. The 1968 Chevelle is no exception. The wiper motor wiring diagram is particularly important as it can be a bit tricky to figure out. In this article, we will discuss the 1968 Chevelle wiper motor wiring diagram in detail.
What is a Wiper Motor Wiring Diagram?
A wiper motor wiring diagram is a schematic drawing of the wiring of a vehicle’s wiper motor. It shows the different electrical connections and components involved in the wiper motor system. A clear understanding of the wiring diagram is necessary when doing any repairs or replacements as it ensures the proper connections are made that will allow the wiper motor to function as intended.
Why is the 1968 Chevelle Wiper Motor Wiring Diagram Important?
The 1968 Chevelle wiper motor wiring diagram is particularly important because it is different from other Chevelle models. The 1968 Chevelle used a three-wire wiper motor, while most other Chevelles used a two-wire wiper motor. The wiring diagram for the 1968 Chevelle wiper motor is unique and must be followed correctly to ensure proper functioning of the wiper motor system.
Understanding the 1968 Chevelle Wiper Motor Wiring Diagram
The 1968 Chevelle wiper motor wiring diagram consists of several components. The wiper switch, the wiper motor, and the windshield wiper assembly are the main components. Understanding how each of these components interacts with each other is essential to understanding the wiring diagram.
The Wiper Switch
The wiper switch is located on the dashboard of the car. It is responsible for turning on and off the wiper motor. The 1968 Chevelle wiper switch has four different positions, each of which corresponds to a different speed setting for the wiper motor. Position one is the slowest speed while position four is the fastest.
The Wiper Motor
The wiper motor is located on the firewall of the car. It is responsible for driving the wiper arms that move back and forth across the windshield. The 1968 Chevelle wiper motor has three wires coming out of it. The black wire is the ground wire, the white wire is the power wire, and the purple wire is the park switch wire.
The Windshield Wiper Assembly
The windshield wiper assembly consists of the wiper arms, the wiper blades, and the linkage that connects the wiper motor to the wiper arms. The wiper arms are attached to the wiper blade and move back and forth across the windshield to wipe away rain or snow. The linkage connects the wiper motor to the wiper arms and ensures that the wiper arms move in synchronization with each other.
