Check the fuses and if they are good then check the brake light switch.
have you checked your fuses?
It can be connection wires, bulbs or fuses.
Check the bulbs - they are doubloe filamented with the smaller being for brake/turn signals Check the fuses
A blown bulb. Check fuses and then start replacing the bulbs one by one.
The probable cause of the brake lights not working on your Renault is the brake light switch. The brake light switch can be found under the dashboard by the foot pedal.
The most likely cause is a defective brake light switch; It is located towards the top of the brake pedal.
Probably the wrong bulbs or the brake lights are getting stuck "on". Or maybe a combination of the two. Check that you have the right bulbs and check to make sure something isn't keeping the brake lights on. FriPilot
Check the switch on the brake pedal
Next step would be to check the fuses
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.
ya its called go to a mechanic you idiot
If the brake lights & horn are on the same fused circuit the most likely cause of the problem is an open circuit before the fuse.
There may be a cut in the wire(s). You will need a Digital Volt Meter to test the wire(s) at your brake light. There is a switch that is actuated when you apply pressure to the brake pedal. If the switch is malfunctioning your lights won't come on.
First, check all fuses. Then see if you are getting power to the bulbs. Then the next possibility would be the turn signal switch.
brake light switch would be most common cause
Brake light switch has quit working. It won't be the fuses, as there is most likely a separate fuse for the high mount stop lamp.
I suspect either a faulty ground circuit, or a much easier fix, faulty bulb/bulbs. You might be surprised the havoc a grounded out bulb will cause an electrical system.
* Brake light switch * Shorted or Broken wires between fuses and bulb sockets * Poor connection in light socket ... clean them out and put a little vaseline on them
To be more specific, the ground wire must work and the bulbs, fuses, etc.. Or the back up lights and turn signals and brake lights wouldn't work? Right? Could it be the back panel...and still let the brake/turn/backup lights work? I need help fast. Thanks!
The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.
BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
check the bulbs themselves they sometimes short out internaly & cause feedback also check sidemarker lights I have changed all bulbs and fuses! Wiring problem???
Possible ground issue at the taillights.
