5000 S window switches

[erict@cta.com (Eric Thorstenson)]

Hi all. Well, I'm getting ready to place and order for several
new window switches for my '86 5000 S, and it occurred to me that
perhaps the old ones may be salvagable. Does anyone know what the
failure mode is on these things? Is it just cruddy contacts, that
could be remedied by disassembling the thing and cleaning? Or is
it more permanent, like something actually broken? Do they even
come apart? (don't have one in front of me at the moment,
unfortunately....)

Thoughts, anyone?
