So my wife’s front windshield washer motor constantly runs from the time the vehicle is started until after the car is turned off emptying the entire reservoir. This just started one day after she drove home from work. I have replaced the motor with a new one, and replaced the column stalk with a new one. The motor still runs constantly without turning off. What would cause the washer motor to have constant power? This is a 2012 bmw 128i. Is there a washer relay somewhere? I see the green relay for the wipers in the fuse box, does that control the washer motor as well?
The system probably runs they some sort of body module, somebody is going to have to diagnos what's happening, you could look at newtis for a wiring diagram
