type 181 wiper motor

Is it possible to overtighten the nut that holds the wiper motor to the windshield frame? I put in a "new" motor that had been tested and was known to work (according to

at least). It moved a little when I first turned it on but then started to overheat and smoke. Did I overtighten the nut or was it a bad motor to begin with?

I doubt tightening hurt it.

Here's what I would do: Disconnect *all* the wires from the wiper plug-in. Find the Red and Green wires which come out of the motor itself. With the wiper frame grounded, touch a Hot wire momentarily to the Red (Hi) wire and then to the Grn (Lo) wire.

If the motor runs at each speed without binding, then I would say there is a wiring problem causing the over heating.

If it doesn't run at *either* speed, look for something jammed in the mechanism.

There is wiper wiring stuff on my web site.

Well, I have the one I'm replacing. The only problem I had with that was a broken bushing or two. So I think what I'll do is simply grab a soldering iron and put the bushings from the new motor in the old one.

I'll let you know how it goes.

Just a guess, but I'd bet that you had the wiper arms attached but didn't have the radial arm adjusted right. When you turned it on it turned a bit until one of the wiper arms jammed against something and then stalled the motor, which promptly overheated.

Remove both wiper arms and try it again.

Hmmm...wow. You're good. The arms did move an inch or two and then stopped. I didn't notice anything blocking the path but I'll do what you suggest and see how it goes.
