For about 2 months now I have been having a problem with my windshield wipers. Basically, they would not stay off. When I had the switch off, they would come on randomly. At first I thought it had to do with when I was taking left hand turns, then it appeared that acceleration caused them to come on, then I finally realized that it was completely random. Sometimes they would go slow, sometimes they'd come on full blast. It was driving me crazy.....
Today, I finally decided to take everything apart and have a look. I thought it may be a shorted wire, and if I could find that I could fix it and avoid replacing the motor. The wires all looked perfect. I then disconnected the harness from the motor- and noticed a brownish slurry inside the connectors. I thought it was some kind of dielectric grease. I couldn't figure out what was wrong, so I returned here and found another thread- where another member had a similar problem and bought a new motor. However, near the end, he mentioned (off hand) that there was "rusty water" in the connectors.
Thinking that I'd have to buy a new motor anyway, so what the heck- I took some rubbing alcohol and splashed it (not too much now) onto the connector housing in the motor, dumped it out and repeated until most of the rust was out. I then took a Q-Tip and finished up to get the last little bit. I gave it a little while to dry and plugged it into the car. With the car on, I could not get the motor to turn on without the switch being on. I tapped it, shook it, wiggled connectors, everything. When I turned the switch on- everything worked perfectly!!! I reinstalled, taped the connectors up with electrical tape to prevent future water from getting in and re-tested and it worked perfectly again!
