The windows will either be a fuse, possible relay, or more likely the motors are bad. The heat / AC in mine had a problem too. It was the cable that switches from cold to hot. It runs from the switch to the driver side where all the duct work is under the dash. There was a plastic lever that broke. I melted a hole in it, and reattached the cable. The headlight motors are usually simple. Pull the motors out, take them apart, clean the brushes with sand paper, add electrical grease, and reassemble. Hope that helps!
