 Posted: Sat Dec 07, 2019 2:51 pm Post subject: Exposed wires at wiper motor |
 |
|
Anyone run into this? And if so, how hard to replace the wires that (I assume) run to the brushes?
Me and the eldest child were driving to the coffee shop in Seal Beach this morning. It started to sprinkle and I turned on the wipers. They worked for three minutes, then stopped. Blew the 15 circuit fuse which feeds several accessories!
We ended up having coffee. Then we drove back home and I went to work. Found the two wires coming out of the motor cover exposed. They were not like that several months ago, THAT I noticed. But sometimes I have tunnel vision.
Anyways, anybody changed these wires out, or is there a rebuilder out there. I am just being lazy. I will most likely remove and rewire the motor, but was interested in knowing if someone else successfully accomplished this task?

Jimbo - there's a seller on thesamba called "wiper guy". He rebuilds wiper motors and assemblies like Tim does carbs. In other words, you get basically a new wiper motor ready to go, no issues. I bought one from him for my '74 2+ years ago, worth every penny.

That's some rough looking soldering, this pic from the gallery shows how it should look:
I wonder if you could get away with detaching each wire and sliding some heat shrink or vinyl tubing down it?

Thank you Victor. I figured there was someone rebuilding these units. But, I am going to try repairing it myself before I go that route. I just never have went any further than removing and replacing, so was curious what the overall opinion of the community was.
I actually did a search on the subject but found no useful information regarding the exact variables.
I will continue to keep this all updated as I work through it. Maybe I will do a wiper motor refresh thread, with new brush wires installed!

That’s what I was thinking. It looked as if a previous PO had soldered the wires. But I could not remember exactly. Been too long since I had to actually look at the wiper motor itself! Funny how things you stop doing, get fuzzy.
The heat shrink idea sounds good. I am just fearful that those wires may have a similar issue at the interior of the motor, so was really wondering if anyone knew for sure before I go removing the motor. That’s a load of work that I do not want to do twice.
Thanks for the idea!

In case the repair doesn't go as planned...

If you don't want to disturb the wires but want to cover the bare copper, liquid tape may be an option. Its like liquid electricians tape.

I agree. If you're worried about water shorting those wires, I'd use liquid tape too. They make it in brushable and spray.

Just my 2C's - here. I had used liquid tape on the crimps of my horn wires a couple of years back and found in recently trouble shooting recurring horn problems, that the liquid tape had run thru the wire before curing, in such a way as to individually insulate each strand of the horn's hot wire, for close to 1/2" back from the crimp. YMMV but I'd go w/out liquid tape for the repair.

That's interesting. I've used it quite a bit and I've never run into that problem.

Thank you! I was so wrapped up in fixing the wires, I did not add up the two visible byproducts of what took place!
Motor is coming out. I will rewire it and internally rebuild it! Thank you!
This is why I posted it up. It was a situation I have never seen before. We get rain, maybe four times a year! Not very common to work or to overhaul this system or its components.
Again, thank you for those 12 words!

Yeah, definitely looks like it shorted somewhere — one or both of those two wires are normally hot w/ the ignition on, I think.
I tore apart, cleaned, and relubed both the gearbox and motor on mine a while back. It’s a bit finicky on couple points (especially w/ the 3 brushes for the motor, when reassembling everything), but certainly doable if you take your time & work carefully. Mine runs much faster and stronger now.
Also, make sure to check the base of the main drive gear (for the wiper arms — it’s some sort of white nylon, or similar polymer I think) closely for cracks before reusing —they’re supposedly prone to that sort of thing there.

If you're worried about water shorting those wires, you should probably fix whatever water entry issue you have.
