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

Tip

Both Lower Brake Lights Not Working


Check Brake Light Bulbs: All cars have three brake light bulbs that create the brake light illumination affect. If the lower two bulbs fail no lower brake light operation will occur. I know what you're thinking, you might say two 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 either 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 Turn Signal Switch: Most American cars are designed to have the brake light switch wiring intergraded into the turn signal switch. Because the brake light bulb and the turn signal bulb are one and the same the turn signal switch interrupts the brake light circuit and installs the blinker signal circuit when the turn signal switch is activated. If this switch fails it will not allow the brake light signal through to the brake light wiring. To test for this condition a car repair manual is needed to test incoming and outgoing electrical current. If brake light switch power is present at the turn signal switch but not at any outgoing brake light wires the turn signal switch has probably failed.

Brake lights dont work, changed the fuse its was ok, changed the switch on the pedal , still not lights. flashers work, turn signal work, but not the brake lights. where to look next


Hi, your van does not use the signal filaments for the brake lights. You must have a wiring issue. Check for power at the brake light switch. If you have power there, the wire is broke from the switch to the S304 junction. If there is no power to the switch, the wire is broken between the fuse box and the switch. Please let me know if you have more questions, and thanks for using FixYa.

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.

Both rear brake lights are out. Fuses are ok. Haven't checked bulbs, seems odd that all bulbs would go out together. I suspect the brake relay is blown, but where do i find that? I looked under the hood...


There is no relay. Therefore, the problem is likely to be the brake light switch above the pedal.
Look up there to see if the plunger comes out when the pedal is pushed. If the plunger comes out, the switch is adjusted properly. Next, try jumping the terminals inside the connector to see if you can get the lights to come on. It should be the 2 outer terminals that run the brake lights. The other (inner) ones shut off the cruise control. Connect the outer terminals using a big paper clip.
If this puts the lights on, replace the brake switch. Let me know if you have questions.

Brake lights doesn't work


Either the brake light bulbs are faulty and needs replacement.But if in case the brake light bulbs checked out ok and the bulbs are glowing by connecting brake light bulb to battery directly ,then in that case the brake light switch is faulty and it has to be replaced./ Check for 12 volts at the terminal in the light socket when the brakes are applied.If there is 12 volt then its a bulb problem ,but if no 12 volt then its switch problem.The brake light switch located under the dash above the brake pedal. ------------ Keep updated for any more queries.Thanks.

Three brake lights went out. Replaced little bulb and it works


hi from uk if all bulbs ok? and ou have checked fuse then the problem is most probably the brake light switch that is stuck in the off position ie the plunger which is supposed to come out and put light on being plastic they do sometimes stick the switch is just above the brake pedal and has a 2xpin plug attached if you unplug and connect the 2 terminals using a wire or paperclip ? then have an assistant check if lights work? if yes then check to see if the plunger on switch is failing to come out when you press pedal ? if yes ? then switch is faulty but if plunger is stuck use wd 40 and work the plunger by twisting and pressing in/out to free it ? then recon the plug and try lights ? if switch is faulty ? easy diy to replace it simply screws out from pedal box assy ten fit new switch and adjust by screwing so lights are off with pedal off and on as pedal is pressed approx 1/2 " to operate lights to on ! this is simply trial/error untill you are happy ? hope this helps best wishes from n/west uk

O2 Dodge Dakota Brake lights wont work but bulbs r good.


If the bulbs are good I would suspect the Brake light switch.

Brake Light Switch: Testing and Inspection
The brake lamp switch can be tested with an ohmmeter. The ohmmeter is used to check continuity between the pin terminals.
Switch Circuit Identification
- Terminals 1 and 2: brake lamp circuit
- Terminals 3 and 4: RWAL/ABS module and Powertrain Control Module (PCM) circuit
- Terminals 5 and 6: speed control circuit
Switch Continuity Test
NOTE: Disconnect switch harness before testing switch continuity.
With switch plunger extended, attach test leads to pins 1 and 2. Replace switch if meter indicates no continuity.
With switch plunger retracted, attach test leads to pins 3 and 4. Replace switch if meter indicates no continuity.
With switch plunger retracted, attach test leads to pins 5 and 6. Replace switch if meter indicates no continuity.

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.
