A windshield wiper is a rather flimsy and delicate device compared to other auto parts, and it is prone to breaking down or just wearing out. There is both terrible news and good news if your windshield wipers quit functioning.

The bad news is that you can no longer see clearly what is in front of you, which increases the likelihood of a collision or other accident. It’s not difficult to repair the wiper motor; you can do it by yourself without the help of plumber.

What is Windshield Wiper Motor?

The windshield wiper motor starts working when you turn on your wipers to clean your windshield. The wiper control switch, often found on one side of the steering column, activates the windshield wiper motor by sending a signal through a fuse and relay to start the engine moving intermittently, slowly, or quickly.

The motor is linked to a device that pushes the windshield wiper arms back and forth simultaneously under the cowl at the base of the windshield. The windshield is cleared as the wiper blades go across it, improving sight for drivers.

Working of Windshield Wiper Motor

Electric motors are used to drive the windshield wipers. The wiper arms are moved by an electric motor that is connected to a worm gear, which transfers the required force to a long rod.

The wipers can move as quickly as they need because the worm gear can produce the necessary energy. The arms impact the actual windshield wiper blades. Rubber blades must exert sufficient pressure on the windshield to remove all moisture without leaving any streaks.
