My VX is in the shop (still - going on a month now!) - I just told them to order and install new regulators, motors, and rubber/felt strips for both doors. Total bill is...well, it's big. I don't think this will cure my window woes, but at least I'll be starting from a known good point - and I can then work from there to hopefully fix things fully (I'm not having my shop fiddle with it - that's a money pit, I think - and they have better things to play with).
