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.

That was the problem. 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.

You are welcome. I live in the rust belt and see things like that too
often. Mine crapped out in the middle of a swamp 1000 miles into a 4500
mile trip. I ran with booster cables hooked up to the motor case for
the rest of that trip.
