My windscreen washer doesn't work. Not unusual I guess. Before tinkering further, I thought I'd have a look at fuses and relays. The relay layout wasn't really what I was expecting. Interestingly disconnecting all three directly in front of the fuse box on the right seems to make no difference whatsover to the working of the car, which is generally pretty good. Everything works apart from the windscreen washer. Anyhow, wondered if there's anybody in the Manchester / Stockport area of England with an X300 whose engine bay I could come and have a peek at? Cheers, Richard.
On second ;look at the wiring Guide the wash pump wiring does not run through the 13 pin connector under the car
In the end the Body Processor Module provides a ground to close the relay on wire Light Green / Yellow so you can cut that wire and provide a ground to test , the body rail coming back from the headlights has ground studs on it
Make sure you check the 2 fuses required for that one specific pump
