Nine out of ten times when your window won't go up or down it is caused by a window motor or the window motor regulator assembly. In most cases the two are replaced as a complete unit. Generally it is harder to get the door panel off then it is to swap out the window motor and regulator. The above diagram shows the typical design of most vehicles and how easy it is to swap out. Of course some cars are easier when they have bolts instead of rivets. For those cars that have rivets, the replacement parts will come with nuts and bolts to use in place of the rivets. Easy enough to drill out rivets and put bolts back in if you don't have a supply of rivets and a rivet gun lying around. In my shop we generally charge around $276.00 parts nad labor for this repair.
