Buick Regal Windshield Washer Pump 93731458 High Durability Alternative

When you press the windshield washer switch and the wipers move normally but the spray nozzles do not dispense water or water flow is weak, and you hear the motor idling or total silence, this usually indicates the windshield washer pump aging or internal blockage, or motor burnout. This pump pressurizes washer fluid from the reservoir to the spray nozzles to keep the windshield clean. This product fits Buick LaCrosse, OEM 93731458; direct replacement. Installation: disconnect battery negative, unplug old pump power plug and water hose, clean reservoir bottom debris, fill washer fluid and test for leaks after installing the new pump.
