My 1997 1500 has an issue where the wipers go up then bind, and the motor hums as it tries to return to 'parked' position. If you nudge it, it follows through to the end and parks. I took the cowl off thinking there was an obstacle in there, but there's no blockage. The motor is working? Because it's trying to return. Is this common? The transmission seems free to turn. I just don't want to buy a motor and find out the problem still exists. Anyone experience this?
Thanks, mike
