94 900's would be the first year of the 'new-generation' 900's unless it's
one of the 1994 'commemerative' classic 900 convertibles? What you're
describing sounds like an earth problem somewhere though.

Check any fuses and relays related to lighting and power to auxilliary
circuits first though, just to rule out anything that can be sorted out
quickly.

On the 2- and 4-door sedan and convertible classic 900's (1979 to 1993 + the
1994 'commemerative' converitbles), there is a well-known problem with earth
connections to the rear light clusters failing over time resulting in very
wierd behaviour of brake lights, indicators, etc.

If you know where the wiring goes at the back part of your car, see if you
can so some visual tracing and you might find something amiss there.

Good luck!

GHolman (GHolman <gholman@dartmouth.edu>) gurgled happily, sounding much
like they were saying:

I'd be looking at the bulbs first off.

Before you get to carried away, I would replace bulbs, they are cheap.
If the high mount works, the circuit is doing something. Is it all of
a sudden you get the "brake light failure" message, or for a while.
The inner light cavities are not
typically used, one of them will light(bright) when the switch below
your foglight switch is pressed, this is a rear fog light, used in
Europe. If you have a test light, and know how to use one, a diagnosis
would be simple. I believe each tail/brake cluster has a dedicated
ground, and for both of these to fail at same time would be rare.
