I believe it deserves mention here that about 98% of all brake light malfunctions do not have anything to do with a blown fuse. In fact, fuses are NOT the CAUSE of electrical circuit malfunctions at all. Electrical circuit malfunctions cause fuses to blow. It is very important when diagnosing electrical circuits, that you understand this basic "cause and effect", so you do not waste time and effort looking for the wrong source of the problem. If there is a blown fuse involved in your brake light problem, you need to find out WHY. Simply replacing a blown fuse will not fix the problem that caused the fuse to blow and will only result in another blown fuse.

With that said, the fuse that protects your brake lamp circuits is Fuse 6B (20 Amp) in the instrument panel fuse block.

HINT: This fuse also protects your hazzard flasher circuits. If these work (front or rear or both) the fuse is not blown.

SOURCE: 95' Buick regal, 3rd brake light works, tail

I dont have a diagram but the brake light switch has to feed the turn signal switch, Either that wire has a bad connection, or the turn signal switch is bad. Jiggle the turn signal lever and see if the brake lights try to work.

I had this same problem. I replaced the turn signal switch in the steering column and it worked great. To test for this, check your lights while wiggling your hazard light button and/or signal lever. When I pulled my hazard button forward, all my lights would come on.

Its the turn signal switch inside the steering column! It knocks out the brake lights particulary the left turn signal! $100 dolar part from the dealer!

Brake lights and rear turn signals dont work in my 2008 dodge charger

If both the brake lights and rear turn signals are not functioning in your 2008 Dodge Charger, there are several possible causes to consider. Here are some common issues that could lead to this problem:
1. Blown fuses: Check the fuse box for any blown fuses related to the brake lights and turn signals. A blown fuse can interrupt the circuit and prevent the lights from working. Refer to your vehicle's manual to locate the specific fuse for these functions and replace it if necessary.
2. Faulty bulbs: Inspect the bulbs in the brake lights and turn signals to see if they are burnt out or damaged. If a bulb is not working, it should be replaced. It's possible that multiple bulbs have failed simultaneously, leading to both the brake lights and turn signals not functioning.
3. Wiring issues: Check the wiring connections and harnesses for any signs of damage, loose connections, or corrosion. Faulty wiring can disrupt the electrical flow and prevent the lights from operating. Repair or replace any damaged wiring as needed.
4. Malfunctioning brake light switch: The brake light switch, located near the brake pedal, activates the brake lights when the pedal is pressed. If the switch is faulty or misaligned, it can cause the brake lights to not work. Consider having the brake light switch inspected and replaced if necessary.
5. Faulty turn signal relay: The turn signal relay controls the flashing of the turn signals. If the relay is defective, it can prevent the rear turn signals from operating. Consider replacing the turn signal relay if other potential causes have been ruled out.
If troubleshooting these common issues does not resolve the problem, it is recommended to consult a professional mechanic or authorized Dodge service center for a more accurate diagnosis and repair. They will have the expertise and necessary tools to pinpoint and fix the specific issue with your 2008 Dodge Charger's brake lights and rear turn signals.

1995 GMC Sierra 1500 3rd Brake Light Cargo Light

This is the only fuse that I can find that deals with the brake lights, but if that fuse had gone, you would have no throttle. My thought is a bad earth. More ideas here. It is a known issue.

2002 foot brake does not make the brake lights come on.

It is possible that removing the LED lights may have caused some electrical issues that are preventing your brake lights from working properly. Here are a few steps you can take to troubleshoot the problem:
  1. Check the brake light switch: The brake light switch is typically located near the brake pedal. When you press the brake pedal, the switch is activated and sends a signal to the brake lights to turn on. Check the switch to make sure it is properly connected and functioning correctly.
  2. Check the brake light fuse: If the brake light switch is functioning correctly, check the fuse for the brake lights. The fuse panel is typically located under the seat or behind the side cover. Refer to the owner's manual for the exact location and fuse rating.
  3. Check the wiring: If the brake light switch and fuse are both functioning correctly, the problem may be with the wiring. Check the wiring for any damage or loose connections. Look for any signs of corrosion, frayed wires, or broken connections.
  4. Check the bulb: If the wiring appears to be intact, check the bulb for the brake light. Remove the bulb and inspect it for any signs of damage or wear. Replace the bulb if necessary.
If you are still experiencing issues after checking these steps, it may be best to take your motorcycle to a qualified mechanic for further diagnosis and repair.

I have a 2005 Dodge Durango. My brake lights are the only lights not working all 3. Every other light works but the 3 brake lights. I've changed the all 3 brake light bulbs and the brake light switch....

If fuse 25 under the hood is good, you have a wiring issue. Are you getting power at the brake light switch? If yes, trace the wires from there to he rear of the truck. If not, trace forward to the fuse.

My inside dashboard lights and back break light suddenly stopped working so cant drive it at night. Its a 99 honda prelude. I've tried changing the light bulbs and the fuse but still not working.

If the dash lights are on the same circuit as the park lights. Chances are if no dash lights... no park lights. Unless the dash light dimmer switch is on the low position. Check park light fuse. If no brake lights... which are on a different circuit and you are sure the bulbs are ok check brake light fuse. If fuse ok, unplug brake light switch at brake pedal and cross the terminals with a jumper. If brake lights work, the brake switch is faulty. If still no brake light operation suspect a wiring issue

1 brake light doesn't work... good bulb and fuse

Lights are usually on a dual circuit! Left and right have separate fuses, check all fuses or check the fuse diagram on fuse cover or manual to identify correct fuse!
