    Wiper Motor

    Wiper Motor Operation:

    Electric (or vacuum on some 1970's and all pre-1966 models) motor that powers the wiper arms. It has built in limit switches that allow the wiper arms to stop at the bottom of the windshield when the wipers are shut off. A set of plastic gears and cranks change the rotary motion into a back and forth wiping motion. Low, medium and high speeds are available and intermittent action through the switching unit. It's also an option on some vehicles.

    How To Instructions:

    Inspect - Check for obvious problems.
    Replace - Out with the old, in with the new.
