My 2015 GLK250 windshield washer stopped working (front and rear). I checked the fuse and it is fine. I gained access to the washer fluid pump and disconnected the connector. I put a meter on the connector, started the car, closed the hood and pressed the window washer button. The wiper move but no voltage appears on my meter. It looks to me like there must be a relay which died.

Does anyone have a wiring diagram, location of relay or some other help to offer? I am happy to just order the relay if I only knew which one and what the part number is.

Thanks
