I own a 1995 Buick Century with about 135,000 miles on it.  When I
drove to work today, I noticed that my anti-lock brake light was on
and wouldn't go away.  The brakes worked just fine though.  Doing some
digging, I found several other issues that weren't there yesterday:
the radio/clock worked, but would lose its settings every time the car
was turned off, the interior lights won't work, the power doorlocks
don't work, the power seats don't work, the headlights won't turn on
(high and low beams).  The hazard lights won't turn on, but I can turn
on either turn signal just fine.  The dashboard lights turn on/off as
usual.  The AC system seems fine.  The power windows roll up and down
as usual.  The car drives just fine - no handling problems at all.

I've checked some of the fuses, and none of them look fried.  I'm kind
of at a loss, and I'd rather not pay the mechanic at the Buick
dealership 90 bucks just to poke around inside if it's something I can
figure out and fix.

Any ideas?
