I would think you could get about $50 or more for the power window motors and switches, someone is always looking to upgrade.  You might not get many takers here or on Pirate, but probably over at 4x4wire or TTORA, you could list them on Craigslist.com(for your area).  The window glass is just one of those things you have to keep listing, until someone comes along who needs it.

Let me know when/if you want some 1/2 doors made.
