How car wiper works
Car wipers help drivers see clearly when it's raining or snowing. They’re a small but important part of the car. Here’s a simple look at how they work:

Wiper Blades
They’re just rubber (or sometimes silicone) strips that slide across your windshield to keep it clear.

Wiper Arms
The metal arms hold the blades and move them back and forth across the glass.

Wiper Motor
There’s a little electric motor under the hood that makes the arms move. It’s usually under the hood.

Linkage
This is a set of mechanical parts that connect the motor to the arms. It makes sure both arms move together smoothly.

Wiper Pivot
This is the spot where the arms are attached to the car. It lets the arms rotate as they move.

Wiper Switch
You turn the wipers on and off with a switch—usually on the dashboard or the steering wheel.

Wiper Relay
This part controls the power going to the motor. It helps the wipers run at different speeds, like slow, fast, or on and off (intermittent).

How It All Works Together
When you turn on the wipers, the switch sends a signal to the relay. The relay gives power to the motor. The motor starts spinning, and the linkage changes that spinning motion into the back-and-forth movement of the arms. They just sweep across the windshield and get rid of whatever’s in the way.

Intermittent Wiping
For light rain, you can use the intermittent setting. It makes the wipers move with short pauses in between.

Washer System
Most cars also have a washer system that sprays cleaning fluid on the windshield. When you press the washer button, a small pump sprays the fluid through nozzles to help clean the glass.
