I know the mk4s have a lot of window probs and have found all kinds of info on them but so far nothing quite like the problem I'm having, bought a 2003 Jetta GLI vr6 about 2-3 months ago my windows have worked fine since but today I put my passenger window up (auto-up one click) and once it was fully up it thumped and now won't go up or down, can hear motor running fine and u can move window up/down by hand and it stays where u stop no prob but motor isn't moving it at all, any one have ne idea what happened to it
