What is a car wiper switch
The car wiper switch is a device used to control the working status and mode of the wipers, usually located on the lever or button on the right side of the steering wheel. By using different gears and operation methods, the wipers can be turned on, off and their working frequency adjusted to ensure a clear driving view.
Switch position
The wiper switch is usually located behind the right side of the steering wheel or near the right dashboard, in a lever style. Some models may be designed on the left side of the steering wheel. For the exact position, please refer to the vehicle manual.

Wiper control mode
The following operations can be achieved through the wiper control lever on the right side of the steering wheel:
