Before you go after the window motors, try this. Lube the glass chanel liberally with clear aerosol silicone spray. Next adjust the regulators by raising the window all the way, loosen the regulator mounting bolts, and bump the switch downward slightly to un load tension on the glass and regulator, then re-tighten the bolts. This usually frees things up and the window moves more freely. If the trim below the doors is not kinked, it can usually be straightened enough to look ok. You mant to install the clips on the car 1st, then the trim. Twist the trim a bit to engage 1 side of the clip, then gige it a whack with the butt of your hand or a small rubber mallet. It installs fairly easily. When you whack it, do so directly over the clip. After you clean the fuse box, apply some dielectric to the terminals to prevent future corrosion.
