    Hi all!!!

    My 2015 Cascadia window washer fluid motor started running non stop. It runs with the ignition on or off. It just keeps running. Any idea how to make it quit? Don’t mind pulling the fuse for now but don’t know which one it is.

    Thanks in advance for any help!!!!

    may have shorted out. remove/replace with a new one. many times a replacement can be bought at an auto parts store. take the old one with you for a match.

    Was it actually running full? We have found that for whatever reason windshield washer is constantly slowly dribbling out dispenser nozzles on some Cascadias. Almost like its got a case of the clap...
    Not sure what the issue was as I just fill out the cry sheet.

    Yep. It was running when it was empty this morning so I thought why not put some washer fluid in it and it ran two gallons out in about five minutes. It actually quit while I was running today so I am hoping it fixed itself although I think it might have just burned the pump motor out. Will fill it in the morning and see what's up. Thanks!!

    Wipers turn on while the motor is pumping washer fluid too?

    No, Just the pump running. It actually quit later that day. Haven't checked to see if it's working now or just burned the pump out. Will update tomorrow.

    Same issue... During heavy and long rain it started to spray liquid non-stop. Took off pump, checked voltage on connector- it is constantly almost 8 Volts with ignition off. Spent hours to find which relay and fuse responsible for this pump - zero result. And now seems like pump went dead after running on empty... Anybody solved issue by yourself or should I go to dealership?

    Typical cascadia problem. The pump is hard wired to sam cab. No fuse for it. The problem is related to water goibg into sam cab... city horn and windshield washer circuits are located close on the board.
