Pontiac Windshield Wiper Motor

The Pontiac windshield wiper is a device used to wipe rain and dirt from a windshield. It generally consists of an arm, pivoting at one end and with a long rubber blade attached to the other. The blade is swung back and forth over the glass, pushing water from its surface away. The speed is normally adjustable, with several continuous speeds and often one or more "intermittent" settings.

Early vehicle windshield wiper is often powered by a manifold vacuum, but this had the drawback that manifold vacuum alters depending on throttle position and is almost non-existent under wide-open throttle. Consequently, the wipers would slow down or even stop. Some vehicles during the 1960s and 1970s had hydraulically driven windshield wipers instead of using manifold vacuum.

This indispensable accessory however has been technologically advanced. And Pontiac vehicles, whether it’s a Pontiac Firebird, Pontiac Grand Prix, Pontiac Montana, Pontiac Sunfire, or Pontiac Grand Am is powered by the Pontiac windshield wiper motor through a series of mechanical components, typically two four-bar linkages in series or parallel. Pontiac windshield wiper motor is buried around the cowl area, between the firewall and windshield.

Pontiac vehicles with air operated brakes sometimes use air operated wipers, run by bleeding a small amount of air pressure from the brake system to the Pontiac windshield wiper motor that’s mounted just above the windshield. Since Pontiac windshield wiper motor is also susceptible to defects, inspecting all the associated relays, connectors and wiring is necessary. However, if it’s stuck in a certain position, you’ve got the option of either repairing or replacing it. Top quality replacement Pontiac windshield wiper motors from highly regarded manufacturers like A1 Cardone Bosch are available in the market for your Pontiac unit.
