Board Computer

The Board Computer on my 91 535i doesn't seem to be "ON". The "BC"
switch on the turn signal lever doesn't do anything and there is an
empty patch on the instrument panel that should light up with
somethin' but doesn't. All of the fuses look OK. I do have the area
on the panel that tells me that the "license plate light" is not
working, and that's true but I don't care about that. Any ideas out
there in BMW expert - land?
