Proper windshield wiper diagnostics?

[m2bandit]

My wipers don't do anything. I checked for juice on both sides of the breaker. Several of the connectors had juice at the motor but I'm not sure what pins are supposed to have what.

I read a post that said I should disconnect the wiper control box and connect the connectors without it and that let some smoke out of my wiper switch. I don't know if that means it's bad or it was bad advice.

I appreciate any advice.

Sounds like something is getting shorted with the wipers activated. Not sure what.

Motor was toast, hopefully that was causing the excess draw.

 

to test for a bad motor:

test light black (ground ) to number 2  (white on wiper motor side can't remember jeep side and I closed it up already ) while switch is set to low

Test light Dk blue /w tracer to black while switch is high

If you've got juice your motor is toast.

That’ll do it! Glad ya found the problem. Have you thought about possibly rebuilding the old one?

Thanks, It looks pretty crusty and possibly bound up on something. I can't move it with the linkage at all.

I read rumor of the 97+ motors working much better so I ordered one. I happen to have some 5 pin weatherpacks so I'll just convert the connectors to that.

Well that works too lol. If they don’t need a core, I’d be happy to take the old one and tinker if you don’t want to keep it.

Sure, let me make sure the new one works in there then I'd be happy to send it your way.

Sweet! Sounds like a plan!
