Wiper Arm Seal | Shaar’s Cars

The seal creates a watertight barrier at the wiper arm mounting point, directing water away from the engine bay and interior components.

The wiper arm seal is a small gasket or seal located at the base of the wiper arm where it passes through the vehicle's cowl panel. It prevents rainwater and debris from entering the engine compartment or interior ventilation system. Over time, this seal hardens and cracks, allowing water to seep in and potentially causing corrosion or electrical issues.
