What is a Wiper Cowl?

A wiper cowl is a protective cover located at the base of the windshield. It encloses the wiper blades, linkage, and motor, shielding them from rain, snow, dirt, and debris. The cowl also helps channel water away from the wiper mechanisms, preventing them from becoming clogged or damaged.

Functions of Wiper Cowls

Protection: The primary function of a wiper cowl is to protect the wiper blades and other components from environmental factors that can cause premature wear or malfunction.

Aerodynamics: Wiper cowls are designed to reduce wind noise and improve aerodynamics. They streamline the airflow over the windshield, minimizing drag and enhancing fuel efficiency.

Aesthetics: Wiper cowls contribute to the overall appearance of a vehicle. They come in various designs and colors, complementing the exterior stylings of the car.
