I'm tearing my hair out trying to get the rear wiper for a my 2002 Mazda Protege 5 working properly.My wife burned out the motor this winter and I've been trying to repair. I've replaced the wiper motor, arm and wiper blade with new. When wiper is turner on it starters but stalls at a couple of positions (about 2 and 1 o'clock) and needs to be helped back to the starting / rest position (otherwise it remains stalled/shuddering).

Seems like some sort or odd alignment issue but I'm not sure. Also not 100% sure about the hatch seal parts that the motor fits thru (e.g perhaps I mixed up the order).
Does any one have any ideas and/or a picture of what the motor hatch seal components should look like assembled? Seems too simple to be this much work!
