Try checking the brake light on / off switch. (BOO switch) It's behind the brake pedal, perhaps it's stuck or need replacement. Also, make sure the problem isn't that your brake pedal is so low that it won't come off the switch, if it is then either your brake booster is shot, or you need a pedal adjustment or other brake work.
The sensor states "check brake lights and brake linings" is this something I can do or must it go to the shop?
I have a 03 gran prix and my brake lights doesn't come on when I go to brake
go to a mechanic
are you sure it is the brake lights and not the tail lights. if it is the brake lights you most likely have a short some where. go to a auto eletrican It is the brake lights which turn on. Short in the switch or the wiring?
Is it the taillights or the brake lights? If taillights it may be a wiring problem, If brake lights check the switch on the brake pedal
brake light switch is bad
Those tail lights could be the brake lights you are seeing and that would be a faulty brake light switch or the brake light switch is out of adjustment.
bad or out of adjustment brake switch on the brake pedal arm
Probably a faulty brake light switch or the brake light switch is installed incorrectly.
More than likely it is the brake light switch that is attached to the brake pedal.
The brake light switch may be out of adjustment or damaged.
its gotta be a ford a problem with the center brake light circuit causes the lights to go out i believe it is a diode
