Is the light bulb inside burnt out. If so, that would do it.
Check the brake light switch first. It is usually near the brake pedal under the dash. A bad turn signal switch can also cause this if the brake lights are also turn signal lights. If the brake lights are independent of the turn signals then disregard the switch problem. A good wiring diagram will help to diagnose the problem also. Check with dealership mechanics as they have access to diagrams.
Brake lights draw their energy from the vehicle's battery.
Brake lights are on continuously while you are driving. Every time the brake pedal is depressed.
GO AND BUY I NEW light bulb !
I suspect your turn signal switch is bad. The power runs thru the switch and it can act up like this when they are bad. You will need to have a mechanic look at yours.
Check the brake light switch it should be connected to the brake pedal somewhere.
Working brake lights are important for safety reasons while driving. It is important to check all of the wiring, if the brake lights are not working and the fuses and bulbs have been checked.
Presumably if both stopped working at the same time the bulbs are okay, but worth checking. The fuses might be fine but the actual connection between wires might be loose/disconnected.
Probably the flasher unit needs to be replaced. This is an electronic switch which usually mounts underneath the dashboard.
you probably need to lift up on the brake pedal a couple of times to reset the brake switch. worked on our 86
How about a malfunctioning brake light switch
Brake light switch on the brake pedal is defective
Check the fuses and the bulbs.
Brake Lights not Stop Lights. Check your Fuses then the Bulbs. Hope This Helps.
AnswerThe bulbs for the brake lights are usually separate from the normal tail light bulbs. Check and replace the brake bulbs first, and if they are still not working examine the fuses, switch and wiring.
try adjusting switch above brake pedal
It needs checked out but both the hazard and brake lights go through the turn signal switch.
