Windshield washer pumpWindshield washer pump (motor) is located at the bottom of the windshield washer fluid tank.In most cars, the windshield washer tank is located behind the front bumper,How it works: When you operate the washer with the switch, it sends the signal to the control module (e.g. BCM) that, through the relay, operates the windshield washer pump. The pump pumps the windshield washer fluid through the hoses that are connected to the washer jets.One of the common problems is when the windshield washer pump electric motor fails and doesn't run when activated by the switch.
