I've tried everything I can think of. Replaced bulbs. Only ones I didn't replace are the reverse lights, which are blown. Replaced both housings and the pedal switch. When I turn the lights on, the tail lights work for a bit and turn off. The top brake light bar works, but only when the lights are on. When I step on the brake, I get the warning on the instrum entry panel "check brake lights". Anyone have any idea what's going on?
