Weather is starting to get bad here and the wifes 2012 BMW 128i washer fluid pump runs constantly. I had to disconnect the pump motor as the pump turns on when the car is turned on, and wont turn off. Could this be a bad wiper relay? Everything was fine, she drove home one day, when she pulled up it just started going off and wont shut off unless the motor is unplugged. Any suggestions would be much appreciated!!!! She's getting pissed lol!
