The 1988 Ford brake light switch does not adjust, replace it with a new one.
You need to adjust your brake light switch. It should be located on the brake pedal. Unplug the switch and loosen the nuts to adjust the button closer to the brake pedal.
Most brake light switches ratchet into position and self-adjust. To reset the adjustment, press the brake pedal part way down & pull the switch out toward the pedal until it clicks several times.
Adjust or replace the brake light switch.
How do I adjust a stoplight switch on my mazda 626 LX V6
Get down on the floor board and look up at the brake pedal arm. You will see a switch that the arm hits when no pressure is applied to the brake. Twist the switch and adjust so when you barely touch the pedal the brake lights come on.
look at the top of the brake pedal under dashboard you can usually adjust them so the brake lights dont stay on.
tighten brake switch located on top of brake pedal under dash adjust so lamps are out and come on with light pressure on pedal.
Move the switch until it opens the contact when the brake pedal is pushed down 1/2".
where is brake light switch
Probably a brake light switch problem. May be able to adjust, or may need to replace. I just replaced the brake light switch in my 1998 Mazda Protege LX and the problem came back. I believe the cruise control could be shorting out the brake light switch.
Out of adjustment. Adjust the mounting of the switch so the brakes lights are off until you press the brake pedal.
