Owning a vintage car such as a 1967 Mustang can be a great experience. However, maintaining and repairing these cars can be a challenge, especially when it comes to the electrical components. The wiper switch wiring diagram is one of the more complicated parts of the car’s electrical system. In this article, we will walk you through the wiring diagram and provide a helpful guide to help you understand how it works.
Overview of the Wiper Switch Wiring Diagram
The wiper switch wiring diagram for the 1967 Mustang consists of three main parts: the motor, switch, and wiring. The wiring connects the motor to the switch, which controls the speed and direction of the wiper blades. Understanding this basic diagram is essential for troubleshooting and repairing any issues with the wiper system.
The Motor
The wiper motor is located under the hood of the car and is responsible for turning the wiper arms. The motor is connected to the car’s electrical system through a wiring harness. It has two power leads, one for high speed and another for low speed. The motor also has a ground wire that connects to the car’s chassis.
The motor is controlled by the wiper switch, which sends power to the motor through the wiring harness. The switch has four positions: off, low, high, and wash. The wash function is designed to spray fluid onto the windshield, which helps to clean it before wiping.
The Switch
The wiper switch is located on the dashboard of the car and is connected to the motor through a wiring harness. The switch has four positions that control the speed and direction of the wiper blades. The off position is self-explanatory, while the low and high positions control the speed of the blades.
The directional function is controlled by a separate switch, which is mounted on the wiper motor. This switch controls the direction of the wiper blades, allowing them to move from side to side.
The Wiring
The wiring for the wiper switch is located under the dashboard and connects the switch to the motor. The wiring harness is equipped with several different wires, including power, ground, and a signal wire, which controls the speed and direction of the wiper blades.
The wiring harness also includes a fuse, which protects the system from electrical surges or shorts. If the fuse blows, the entire wiper system will stop working until the fuse is replaced.
