- 99 Mercury Mountaineer
I have a 99 Mercury Mountaineer and one day after work my front wiper pump quit pumping fluid. The rear works perfect. I figured since the rear worked fine, and the front quit working it was my multifunction column switch. I replaced that switch and it was the same thing. After that I disconnected the wiring harness to the pump and metered it. Not surprisingly, when I hit the rear switch it metered fine (12 volts). When I metered it for the front washer pump it only reads 1 volt. It seems to me since there is only one pump for both the front and the back that it works as a polarity switch so there must be some sort of relay that Im not aware of at work here. Could someone point me in the right direction? Not having a front washer pump in Minnesota in winter is not a good time.
