'''Problem:''' Window goes down but not up, moves but the action is very jerky, or won't move at all.

'''Likely cause:''' Window switch internal electrical contacts are pitted/corroded.

'''How to check:''' Swap with a known good switch.

'''Repair:''' Replace switch or disassemble switch and clean/restore contacts.

If you choose to disassemble the switch, watch out for springs or clips falling off the switch. Pry the switch halves apart with a small screwdriver. The switches have a high current going thru them, and the internal contacts tend to pit and arc, especially after 20+ years of use.

Clean the contacts with your favorite tool (well not your FAVORITE tool...(cough, cough)...). I've used a Dremel with brass brush, a scotch-brite pad, and a drafter's electric eraser (kept from the days before AutoCAD).

I've also restored a set of severely pitted contacts with silver solder. Of course it won't last as long as the originals, but it will get you through a weekend or a work-week.

For the later illuminated switches, the bulbs are replaceable.
