Saab: 9000 CSE power window switches

The center console window switches in my 98 9000CSE work only
intermittently, specially the back windows. The switches at the back
doors work fine. I am guessing that the contacts are dirty,
especially considering that their horizontal orientation is an
invitation to dirt. How can I get the center consoles switches out
without causing any damage? My service shop warned me that I would
end up with "a hundred parts" in my hand if I tried to do it myself
and recommended a new switch assembly at $300US. Thanks for any
suggestions.

I believe that it is not the switches, but some other relay or fuse. In
my 1993 9000 CSE, the window switches sometimes don't work in the morning
immediately after starting, but works 5 minutes later on my journey.
