    Having problems with both the wipers and washer pump. Wipers only work on high speed. Washer pump doesn’t work. Replaced wiper motor, switch and washer pump and nothing. Checked relays and fuses and are good. Any ideas? It’s 2009 kw w900 with a c15.

    Sounds like Circuit breaker or fuse, sometimes they fall out. Last six of VIN for wiring diagram.

    Can you get me a wiring diagram for my washer wiring? Mine stopped working so I have it temporarily wired to a toggle switch. The last 6 of my vin is 330301

    Here is the diagram. T/S would be easier if you had ESA. If your wipers are wiping when selecting washer but pump isn't operating, I would suspect fuse G8 in chasis load center (under-hood fuse panel) is blown or open in wire YEL5913-0 from chassis load center to pump. Let us know what you find.
