They usually want to sell the doors intact. There are quite a few yards around me, and usually the only way they will sell the components is if the door is too badly damaged to sell. Or you have to get lucky at a pick and pull yard where you can pull your own parts. They don't care as much.Have you looked on
http://www.car-part.com? There are a few places listed on there in Canada with power door regulators, motors, etc. But you can expect to spend like $100 per door, probably more, for just the windows.There are also several places on ebay that are parting out Vibes. They just list like one part in the ad, but show the complete car in the pics. Maybe ask some of them? But your best bet is to find someone parting out a power package Vibe. Have you checked with the guy on here parting out the Vibe?
