Brake light switch near brake pedal
ABS system is inoperable and there is something wrong with the non-ABS part of your brake system.
Check your fuses both inside the cab and under the hood
Because something's wrong, of course. What it could be... bad switch, break/short in the wiring, bad fuse or relay, or even just bad bulbs.. chances are, your car uses dual filament bulbs for the brake lights, where they'll function as both marker lights (with one filament active) and brake lights (with both filaments energized).
may have the wrong type bulb check to make sure bulb has two contact points.
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?
It needs checked out but both the hazard and brake lights go through the turn signal switch.
your brake light switch is probably out
If you have recently replaced the taillight/brakelight bulbs... you may have installed the wrong type. This will cause the circuit to cross and light up both filaments, which would look like a brake light.
Brake Lights not Stop Lights. Check your Fuses then the Bulbs. Hope This Helps.
in the fuse box
you need a new brake booster
HeyKris==It is probably the switch located on the brake pedal. GoodluckJoe I am having the same problem but shouldn't both the top light and the break lights be activated from the same switch? Is there anything else it could be?
