00 E.B. : Replace Rear Window Wiper Motor or ?
 

My 2000 Eddie Bauers rear window wiper motor has not worked regularly for a while, I try it every once in a while just to see if it is working. It has started back up for short periods of time so I think it is a short or bad connection, but I do not know where to start. I pulled the panel off and everything seemed to be tight, but I am not sure how to proceed. I would really like to be able to fix this motor without replacing it if possible, but I do not know how to troubleshoot it.

Thanks,
Randy
