Default Intermission failure

Quote:
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!
I have a similair problem, my intermission is acting up. High works, low works, intermission works, but does not shut off the wipers. They are always on until I hit the dash, out of madness, or they just stop on their own.

My mechanic, which is very good, thinks that the motors are fine and that it caused buy the cold grounding out a wire some where. He also loves this forum, because I used this forum to help-him-to-help-me fix my 120PSI problem. I think that it is a ground as well, but in theses newer cars anything can happen.

Any thoughts guys? :goodmorning:

Well, it could be a corroded or damaged switch, or a bad wire. If the motor is turning on by it'* self then I would guess the motor is fine. See if you can clean the contacts in the stalk switch.
