How do you fix a windscreen washer on a Mitsubishi l300 van?

To fix a windscreen washer on a Mitsubishi L300 van, first check the washer fluid reservoir to ensure it's filled. If it's full, inspect the washer pump and fuse; the pump may be faulty, or the fuse might be blown. Check the hoses for any blockages or leaks, and clean or replace them as needed. If the pump is not working after testing, it may need to be replaced.
