Noisy windshield wiper motor

A few days ago I went to clean my truck's windshield and activated the washer switch. The pump spayed washer fluid like normal but as soon as the wipers started moving there was a lot of motor noise. It was definitely wiper motor noise because it only made the sound when the wipers were moving. Now at this point I haven't checked to confirm if it's the motor or maybe other wiper mechanical parts making the noise. It really sounds like its the motor, though.

I've never had any vehicle that had a windshield wiper motor issue. Any experiences would be welcome.

No one has had a noisy windshield wiper motor? I'm guessing its pretty rare. I've never experienced this in any vehicle I've ever owned.

I think I'll have some time this weekend to disconnect the linkages and isolate the motor. If I confirm that the noise is coming from the wiper motor, I'll replace it.

If you can actually take the motor apart you may be able to "rebuild" it. Just seems these days things are meant to be throw away items. I was able to rebuild some switches and motor controls on my old Benz, but ti was built over 40 years ago.

Make sure you mark the linkage with a paint pen so you can put it back together exactly the same way it was...

Thanks, CO! That's probably some really good advice and I'll be sure to do it.

I just "rebuilt" the garage wall control box for my Liftmaster garage door opener. The wall control box was triple beeping about every 30 seconds or so. Quite loud and very annoying while in the garage. I did a lot of research and found out that the problem was a couple of small capacitors that go bad. Someone on the Liftmaster forum posted a link to buy the correct capacitors for less than $2. They arrived at my house in two days and last night I pulled out the soldering iron. My wife helped me and we removed the two bad capacitors and soldered in the new ones. Installed back on the wall and no more loud, triple beeping. Everything works like new.

Yes, I would love to rebuild the wiper motor if it didn't take hours and hours to do. It sounds like a bearing or bushing is bad.
