Does anyone know how to replace the brake switch on a 2004 x-5? I checked the bulbs and fuses and all were in tact. The only thing I could think of as to why the brake lights weren't working was the brake switch. Thanks

did you test the contacts on the brake light assembly itself? sometimes i found that a little corrosion will make all lights fail. if not
