2015 C Class windscreen washer pump issue
Hi,
My windscreen washer isn’t operating when pressing the button on the stalk but the wipers are wiping when pressed. I thought the pump had failed so replaced it and still the same issue. I tested the original pump off the car and that’s fine so put that back in the car but still no power to it when pressing the button. I plugged in a diagnostic tool and found the module to test and it works fine, just not on the button on the stalk. Could this be the stalk it’s self that needs replacing? Although when pressed the wipers operate so I thought it would either all work or nothing. Any suggestions? Thanks, Dan.

It is relatively cheap to replace the windscreen washer pump, I'm showing about $20 for the part and less than an hour labor.
