Windshield wiper

[bstarr3]

I had perfectly working wipers until yesterday. Now the passenger side wiper doesn't move. It will move maybe five degrees then it falls back down below the line where it started. The drivers side rotates fine. Is there some kind of linkage between the two wipers or is the passenger side motor dead? I've understood it's a real pain in the ass to replace the motor. What's the diagnosis and troubleshooting like for this problem?

sounds like maybe the splines are stripped on the passenger side one, either the wiper arm splines, or the motor linkage splines...take the passenger arm off and see if the little nub rotates in sync with the driver side wiper, if it does, its probably not your motor. visually inspect the splines to see if they are flattened or buggered up.
