How do you fix windscreen washer system?

To fix a windscreen washer system, first check the washer fluid reservoir to ensure it's filled. Next, inspect the hoses for any cracks or blockages and the pump for functionality; listen for a humming sound when activating the washer. If the pump is not working, it may need to be replaced. Lastly, clean the nozzles to ensure a proper spray and check the electrical connections for any faults.
