The light/lights in question have probably lost their ground. Pull the lights out and check for any bad connections.

I have a 2000 Pontiac grand Prix GT, I have a problem which GM is aware of. No brake light, third light works in rear window. Bulbs are ok, Fuses are ok. Help


If your third brake light is working then the fuse, and brake switch are ok (it powers up all brake lights). The most likely cause is the column mounted multi-function switch, it consists of the turn signal, hazard and brake light controls, on the right side of steering wheel. You can check at the base of the column. There is a large black three-piece connector there that all the ignition, starter, lights, horn, cruise control and wipers all go thru. With the brake pedal depressed there should be power on the white wire (its on one of the end connectors terminal 1, very first wire, and should have pink wire directly beside it). If power is good, then check for power on the opposite side connector dark green wire terminal 6, and yellow wire terminal 7 (there are near the center directly beside each other). If no power on either (green or yellow) then the multi-function switch is at fault. If power is present on both, then the rear signals must also be out, and you'll have an open connector going to the rear lights.

95' Buick regal, 3rd brake light works, tail lights work, turn signals work, stoplight switch seems to work ie 3rd brake light working, fuse is ok, changed bulbs, but no rear brake lights.


If the third brake light works and the regular ones don't, it is most likely a bad turn signal (multifunction) switch. The switch is able to kill the brakes lights to run the turn signals, and in rare circumstances does this. I've seen it several times. It could also be wiring, especially near the turn signal switch, but it is usually the switch.

2001 f 150 extended cab. trailer lights were working. had to replace a trailer light uhit because it was broken. now lights do not work properly. running lights work. turn signal only works if running...


The description of the problem is very confusing. If the trailer is disconnected, do all of the functions work OK? If so the problem is with the trailer wires. If all worked before you replaced the light, then thats where the problem lies. The turn signal/brake lights are a seperate circuit than the running lights. The brown should be hot with running lights, and the yellow and green are the turn/brake signals. The trailer lights should be grounded to the trailer frame, and the frame connected to the white wire, Make sure the white wire is connected to the plug on the truck side and connected to the frame of the truck. The turn signal that works with only the running lights on doesnt make sense, and grounds are the most common item. Some Ford trucks have seperate fuses for right and left. There a small fuse box under the hood, near the brake booster.

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.

Brake-light / side-light electrical problem


follow the light my son..stay away from the switches and relays...your solution lies in the powers/grounds at the chassis /bulb areas...the grounded power to the front bulb is causing brakes to go on..(they are ground actuated )....so you are closer than ever to solving this ..go back to each location making sure that they are clean , grounding to chassis and getting power... the gremlin will go away when ALL are power/ground happy
