I've just swapped the one from my non-working gti into my jetta and the plug i'm currently using to block the newly opened hole isn't the best. Its one of those 'screw-in rubber hood holder-upper when closed' plugs for lack of a better explanation. Its a great fit but sometimes the wiper will go past the molding and knock it out, or get stuck on the opposite side of it.
what sort of plugs are you guys using for yours?
Also to address the over rotating problem i assume just unscrewing and rotating the wiper would fix it, but sometimes if its going slowly it stops above the registration (ny fwiw). is there any way to control it better? or regulate it short of the #99 fuse?
oh, and how do you guys get it to stop in the middle?
