hi i have been having trouble diagnosing a problem with my Mazda 3 bl 2010 . the brake lights stay on, but when i pull out the 15 amp room light fuse the brake lights work as normal. i have tried 2 different brake switches with no fix even when there is no switch the light stay on. i have heard that there is an abs pressure switch in the abs module that can cause this issue does anyone know if this is true?? any help or advice would be appreciated
