why doesn’t my brake light work?
The first clue i had that the brake light switch on my 87 Ranger was bad was that the cruise control would not shut off when I tapped the brake. Checked the brake lights and of course they were not working.
If none of your brake lights are working the BLS is a prime suspect.
One not working is probably a bad bulb and your owners manual will give you the bulb info & might tell you how to change it.
