Re: Wiper / Ignition Wiring?

Do you have an intermittent wiper module under the dash?

Hi Mike, No it is just low and high speeds. No module that I've seen. I'll look though.

Ok, sounds like you might be on to something. That park ring will be sucking some juice maybe.

I would snip that black wire going to the motor from the switch someplace easy to fix later and see what happens.

When you had the motor apart, did you notice any burns or marks inside on a copper or brass ring that goes part way around the end of the shaft?

Was the brass ring maybe in upside down? The opening in it has to be in the right place for park.

The black wire feeds this ring for park power and when the motor gets to one point, a contact slides off the end of the ring into the opening stopping the power and parking the wipers. The contact is a ground tag. Or the ring is the ground and the contact is the black wire from the switch, don't remember.

You know Mike, the wipers stop wherever when the switch is turned off. They don't park in the down position like most vehicles do. They never did though, even before the disassembly of the motor.

Those are the rings. They can be repaired if worn. Hard silver solder or lead free solder which is pretty hard can fill up the low spots. Regular electronic solder is way too soft.

I would see what happens when the black wire is off. If it works, then I likely would leave well enough alone unless I got ambitious one day...

The rings your referring too are the copper ones located on the plastic plate? These showed signs off wear. The one contact brush didn't look too good either. The wipers work fine though. I just need to turn the switch off when they reach the right spot on the windshield. I'll disconnect the black and see what happens.
