Is Your Windshield Washer Pump Failing?
When a washer pump fails on the XJS, the symptoms are usually obvious. You push the button to wash your windshield and nothing happens. If you don't hear the familiar humming or buzzing sound of the pump motor, the pump itself has likely failed. However, sometimes the pump runs, but you only get a weak dribble of fluid, or nothing at all.
Check for Clogs First
Before you replace the pump, it's wise to check for other common issues. The washer system in the XJS has several points where clogs can happen. The small filter screen on the pump's intake can get blocked with sludge from old washer fluid.

Choosing a New Aftermarket Washer Pump
