for now with your windows try spraying some silicone lubricant in the tracks and/or cleaning out the tracks.. worked wonders for my windows

i dont think theres anything you can do about the cd changer.. i have one for sale i pulled from my vx in working condition if youd like it PM me... look in the how-to section for a description of how to get your CDs out of the broken one

if you havent done it already id download/burn a copy of the VX repair manual from www.tonemonday.com (in the VX parts section) it helps with problem diagnosis and part locations
