Re: the power window switches.

I've disassembled them before and cleaned them. As I remember it, the key
success factors are a clean work area (parts may snap out), a good
degreaser, a good light grease (say fishing reel grease), and some small
screwdrivers and perhaps pliers. IIRC, it took patience and a steady hand.
But the end result was successful.

A side note: I'm surprised the bulbs on the window switches keep working
years (and miles, or perhaps run-hours) after their installation. I
believe they're illuminated whenever the ignition is on.

I know that replacements were available at one time through list vendors
or list members, but that the wiring harness would have to be reinstalled.
Not a big issue, IMHO.

Good luck.
