Brake Light Circuit Problems

["Vellender,Patrick M.(NXI)" <Patrick.Vellender@xxxxxxx>]

> I've got an 89 535i (E34) and am getting the message "Brake Light Circuit"
> on my dash display when I first press the brake pedal after starting the
> car.  I checked and sure enough my brake lights are not working.  The
> tail, reverse, turn signal, head and fog lights all work.
> 
> I swapped out the working turn signal bulbs with the suspect brake light
> bulbs and the brake lights still don't work.  The turn signals work fine
> with the bulbs from the brake lights so I know its not the bulbs.
> (Although I need to check the 3rd bulb, I don't think that this will be
> the problem.)
> 
> Any ideas as to what it might be?  I'm thinking maybe the switch connected
> to the brake pedal.
