What does a Windscreen Washer Pump do?
The windscreen wiper / washer system enables you to clean your windscreen while driving. The washer fluid assists the window wipers to clean the windscreen of dirt, debris and, moreover, also acts to protect the window from scratches as the rubber wipers move over it. The washer nozzles that distribute the washer fluid over the windscreen are powered by the washer pump that is mounted in the engine bay.
How do you know there is something wrong with the Windscreen Washer Pump?
- When there is no washer fluid coming from the washer nozzles.
- When there is an irregular supply of washer fluid coming from the washer nozzle.
When should you consider a Windscreen Washer Pump replacement?
Over time, the windscreen washer pump's condition can deteriorate and ultimately it can fail. It is likely your windscreen washer pump has failed when there is no washer fluid distributed onto the windscreen. In most cases this would mean there is no noise coming from the pump when it is activated by you.
That said, when there is no washer fluid being distributed over the window it is not necessarily the washer pump that has failed. In some cases it might be that the wiper switch has failed or that the system has blown a fuse. Equally it could be a loose or corroded wire connector. At an inspection the mechanic will establish, step by step, what the exact fault in the electrical system is before replacing any parts.
When there is a noise coming from the windscreen washer pump when activated but no washer fluid is distributed across the windscreen the fault most likely lies with a non-electrical issue. The most obvious one is that the washer fluid reservoir is empty, in other cases it might be that the washer lines or nozzles are clogged up preventing washer fluid to flow through.
Should you experience problems with the windscreen washer facility then it is advisable that you have it inspected as soon as possible. If necessary, have the windscreen washer pump replaced. Always remember to service the windscreen washer pump as and when stipulated in the guidelines set out by your car's manufacturer.
