The wipers quit working on this vehicle without warning. Fuse is fine checked voltage at switch. Battery voltage at white wire with key on, Battery voltage at gray wire on low, no battery voltage at purple wire on hi just 4 volts. Washer and delay don't work either. I supplied voltage directly to washer pump comes on no problem. Could this be a bad switch (a pig to replace?). Or could it be the circuit board in the motor. Checked the voltage at switch and the connectors on motor. Would a bad circuit board stop washer from not working too. Took it out appears to be fine no cracks. |

I find the grounds up and die easy. I would run a battery booster cable from the battery negative to the wiper motor case first. If it then works, I would be looking for the bolt that has the metal ground strap under it.

A short metal strap from one of the mounting bolts that is grounded to the motor was broken off. Wipers running now. I don't know why I never thought of that the first time.Thanks for the advise. jason_39 (AT) hotmail (DOT) com wrote: The wipers quit working on this vehicle without warning.
