Bad turn signal flasher? Bad turn signal switch? Blown fuse? Bulbs burnt out?
It' likely, if bulbs are OK that the turn signal switch is burned out. If the switch fails, it won't allow the brake light signal through to the brake light wiring. Go to:http://www.2carpros.com/first_things/no_brake_lights.htm for the 4 page analysis. See: "(American Car) Both Lower Brake Lights Not Working" To determine if the switch is bad test the incoming and outgoing current. If brake light switch power is present at the turn signal switch but not at any outgoing brake light wires, the turn signal switch has probably failed. This is a Buick design issue because keeping your foot on the brake or if the brake switch sticks keeping the brake lights on, the circuit will fail due to amperage overload.
Sounds like it's not your bulb that is bad. It may be your brake switch isn't working.
