Rear wiper not working

[dmwelch54]

I replaced the motor and it ran OK for a couple of days, now when I turn it on, nothing. The washer works and fuses 43 & 50 are good. Thoughts? Dale

What's the model and year?
Could be a faulty replacement motor.
Is it a new motor or s/h? OEM or pattern part?
Possibly a wiring fault that you disturbed while changing the motor so that it overcame the fault for a while

I had a go at the contacts and pinched plug winged connectors and now working as expected. MMyMB mechanic says the connectors on this model are crap...

Could have been that the original was fine then.
Always prudent to do a V test first.

.....

While I don't disagree with you .... .... having voltage isn't always the answer. Many many moons ago I drove my brother-in-laws car & discovered there was no interior fan, so set about it with a multi-meter etc. There was voltage at the fan, but it wouldn't work. I applied a feed to it directly from the battery & it worked It turned out that the wire feeding the fan through the bulkhead connector was all but sheared - just a couple of strands of wire surviving- so, though there was voltage, there was no way it could feed the fan enough current.

Just saying

That is a valid point. I had a alternator fail on a garden tractor once. It had me stumped for months. it was putting out V but not current to charge the battery (a certain type
of briggs alternator - spare the detail) . So I knew it was working but not wanting to spends 130 on some magnets and coil - On close inspection of the cable there must have been 3 strands of copper wire sheared out of a connector. A blob of solder and it was prima.
