The brake light circuit does not have any relays except the filament monitor which is located in the luggage compartment.
At the brake switch, is voltage available at Red wire at all times?
Is voltage available at White wire when brake pedal is depressed?
If yes to both above, test the White wire ( Terminal # 9 an 10) at Filament Monitor for voltage when brake pedal is depressed. If voltage is available, test the output wire to brake bulbs for voltage. If no voltage is available, check the Blue/White wire (EDB fuse # 29 and 30 ) for voltage. If voltage are avail, chack the ground circuit, and if all works accordingly, substitute a monitor to test.
