Help with Wipers Not Working

The windshield wipers on my 2004 Prius recently stopped working. They stopped in a position at approximately 45 degrees. I can't move them manually. When they first stopped, they would jerk a bit, as if they were trying to move, but never leave that general position, although that stopped after a while.

When I asked a mechanic about it, he told me that those symptoms indicated a broken motor. I bought a used motor and installed it, but the wipers still don't work. I suppose the used wiper motor could be broken, but I'm guessing something else is the problem.

Any suggestions?

 

Thank you!

I just went to the website. It's an expensive subscription. Have you found that site to be reliable in providing information? I'm a little concerned about paying for a subscription then not getting the information I need.

Thanks!
