There is a switch under the dash on the brake pedal. Unplug and jumper it to see if the lights come on. If so, replace the switch.

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!

My additional brake light is not working i have tested the brake unit and that works is there a seperate fuse for this or is it all on one fuse for all the brake lights


The third or High Mounted Brake Light runs straight off the brake light switch on the brake pedal arm. You say you tested the "brake unit"? I assume you mean the third brake light assembly, and if you get power there when someone steps on the brake pedal, then the bulbs are bad.

The power flow for the brake lights goes like this: Fuse ->Brake switch -> Turn signal switch -> Rear lights. The only difference is, if you have a 3rd brake light in your rear window, that gets its power directly from the brake switch. It does not go thru the signal switch first. So, if you are having a brake light problem, and your fuses are good, check the 3rd light in the rear window, if it lights up (assuming the bulbs are good, no one ever changes them), then the problem is most likely in the turn signal switch, hope this helps!

My tail light not working


Which light?
One light not working? Check the bulb.
Both tail lights not working? Check the fuses and the bulbs.
Brake light (or lights) not working? Check the bulb, fuses and brake light switch.
Totally no lights in one or both tail light assemblies? Check the plugs on the light assemblies from inside the car. Check the fuses. Check the grounds (might be some under the dash for those lights).

Brake lights not working on 2003 E 350


Have you checked the fuse for the brake lights and have you checked the brake light switch.
The brake light switch is directly above your foot when it is placed on the brake pedal.

Brake lights do not work All bulbs have been replaced.


Troubleshooting Procedures - Read Completely Before Beginning
(American Car) All Brake Lights Not Working
  • Check System Fuse: A fuse is used to protect the brake light circuit from amperage overload. If the fuse has failed it will not allow the electrical current to continue to the brake lights. To check the fuse, first locate the brake light system fuse in the fuse panel which is either under the dash or under the hood in the power distribution center. Connect the test light to a ground like an engine or dash bracket and turn the ignition key to the "on" position. Using the test light probe both sides of the fuse. If the test light illuminates on both sides the fuse is ok continue onto the next step. If one side of the fuse illuminates the fuse has failed and needs to be replaced. If the fuse fails as soon as it is replaced or when you apply the brake pedal the brake light electrical circuit is shorted to ground. Rarely a system short can occur, a car repair manual is needed to find the wiring schematic for the brake light circuit. Once the brake light wiring has been located inspect and repair as needed.
  • Check Brake Light Bulbs: All cars have three brake light bulbs that create the brake light illumination affect. If all of these brake light bulbs fail no brake light operation will occur. I know what you're thinking, you might say all three brake lights at once? But in reality one brake light went out at a time and you did not notice. People only tend to notice something when they almost run into the back of your car to help persuade them to inform you the brake lights aren't working. Remove any of the brake light bulbs to confirm the bulb is ok or burned. After the bulb has been removed inspect the filament and replace if failed. If the brake light bulbs are ok continue to the next step.
  • Checking the Brake Light Switch: A control switch is used to connect the brake light electrical circuit. This switch is located near the brake pedal lever. Basic switches have just two wires, power in and power out to the turn signal switch. Use a test light that is grounded and with the key in the "on" position test for power at one side (wire) of the switch, then press the brake pedal while testing the opposite side (wire). It should illuminate the test light, if electrical power is connected through the switch go to the next step. If no power is detected through the switch the brake light switch has failed and replacement is required. If your car is equipped with more than two wires integrated into the brake light switch a car repair manual is needed to locate the proper brake light circuit wiring.

Left rear brake light stopped working but bulb and fuses are OK.


These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!
