Windshield Washer Pump Replace

Overview



1/2
The Windshield washer fluid pump is provided power to spray washer fluid on the windshield. As washer pumps get old or defective by an electrical surge, they can not provide the power to wash the windshield. An obvious indicator that your washer pump is failing that with normal washer fluid capacity, when you press the switch of the washing windshield, there is no washing fluid spray out. Btw, the windshield washer pump was controlled by the SAM control unit, there is no fuse for the pump. So there will no indicate on the dashboard, also no failure code was saved.
