Power Source for Windshield Washer Pump on a '94 Camry 6cyl

[i_am_jim]

I bought a windshield washer pump, removed the wheel liner, installed the new pump -- nothing.

I measured the voltage to the pump and it jumped all over the place. Usually between 4-8 volts changing constantly. I think it's supposed to be 12v steady so, I assume this must mean the pump wasn't the problem, it was the power to it.

Anybody know what to do when the voltage to the washer pump is bad? I have no idea where the wires come from. I assume they're from a relay somewhere, but I guess they could come from the windshield wiper motor.

It actually runs from the 7.5A fuse behind the coin tray, to the Wiper switch, then from the wiper switch to the Wiper motor. If your wipers work, your fuse is good. So its either the switch or the wiring.

Most likely the switch is causing your problems.
