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!

Third brake light does not work after changing the bulbs


If some of the lights work then you probably don't need to change the light assembly. My first guess would be a burnt out fuse. Look for the fuse box and remove the cover. Usually on the inside of the cover it will have a diagram for all the fuses and you can find the one for the brake lights. Some vehicles have relays that are fried and these may be under the hood. Just look for a black box which contains electrical relays and other fuses. The last thing I can think of is a switch that is right above the brake pedal. When you apply the brake a small plastic or metal extends and this is what makes your brake light come on. www.lightdeal.co.uk

Kia picanto rear brake lights will not turn off


Check the brake light switch on the brake pedal. It may need adjusting to allow brake lights to go off. The plunger on the switch needs to open when pedal is depressed, and close when pedal is released and in its normal position.

The brake lights do not want to work. i have changed the brake switch under the dash and the bulbs on the tail lights.still nothing. i also, changed fuses.


does the high mounted brake light work? the brake switch has 2 contacts one for the high mount (LT BLUE/BLACK) and one for the tail brake lights. The tail/brake light wire is LIGHT BLUE. the main connector between the brake light switch and the tail lights is C208 which is located behind the rear seat, left side. So if there is power coming out of the brake switch OK and no power at the tail lights, check that connector. Hope this helps.

Have a 1999 Chev. Suburban. Problem is with brake lights. Top panel (on roof) works but neither side panel works. Replaced circut boards in tail lights, new bulbs, and all fuses are good. What next?


WITH A GOOD FUSE TESTER, TEST ALL THE FUSES FUSEBOX UNDER THE HOOD & INSIDE THE VEHICLE. IF THE FUSES ARE ALL GOOD WITH THE TESTER YOU MUST HAVE A BAD BRAKE LIGHT SWITCH OR A BAD TURN SIGNAL SWITCH. THE BRAKE LIGHT CIRCUIT GOES UP THROUGH THE TURN SIGNAL SWITCH & THEN TO THE BRAKE LIGHTS. FIRST OF ALL IS THE BRAKE LIGHT SWITCH GOOD ? THE ORANGE WIRE FEEDS THE BRAKE LIGHT SWITCH, THE WHITE WIRE PUTS POWER TO THE TURN SIGNAL SWITCH, SO THE LIGHTS CAN BE USED AS TURN LIGHTS OR BRAKE LIGHTS. , PUT A TESTER IN THE WHITE WIRE & PRESS ON THE BRAKE PEDAL. IF THE TEST LIGHT LIGHTS UP, BRAKE LIGHT SWITCH IS GOOD, BY THE WAY THE BRAKE LIGHT FUSE MAY BE LABELED" STOP", THE FUSE LABELED" BRAKE" IS FOR THE ABS SYSTEM. TO CHECK THE TURN SIGNAL SWITCH FOR BRAKE LIGHTS, REMOVE THE PLASTIC COVER FROM UNDER THE STEERING WHEEL, PRESS ON THE BRAKE PEDAL, PUT THE TESTER IN THE SMALL YELLOW WIRE, THEN THE SMALL GREEN WIRE. IF THERE IS NO POWER IN EITHER WIRE, THE TURN SIGNAL SWITCH IS BAD.

My break lights don't work


have you checked for blown fuse under dash in fuse panel? if so, are brake light bulbs blown ? if not, check on brake pedal for bad brake light switch, it will be above the brake pedal on the arm assembly, look for a black switch that has wires running to it, it may only need adjustment. it has a plunger type switch, when it moves the brake lights come on, when it closes the circuit, the lights go off..hope this helps and thank you for choosing fixya.com!!

My brake lights do not come on when i press the brakes. i have changed the switch for the brake lights but I still get nothing, which wire do I need to change because the brake light wire on my 2000 Esteem...


If you have a meter.... check the bulb socket for 12V DC with someone applying the brake or watch for a 12V DC pulse on the meter when the meter leads are on the socket contact with the emergency flashers on. (+) lead to socket contact and ( - ) lead to chassis ground. If you have the 12V DC on the socket contact then there is a problem with the chassis ground wire.
The brake light socket has 2 terminals. One is for the tail light 12V DC power when the headlights are on and the other one is 12V DC only when the brake lights are supposed to be on. (i.e pulse hazard or brake applied light on)

Also check the BRAKE light fuse in the fuse box located on the front of the left kick panel wall drivers side with a black cover. (4" x 2.5") There is also a fuse and relay box on the left side of the engine compartment. (4" x 7")

The wire color connected to your NEW brake switch that leaves the switch for the tail lights is the same color on the rear of the car and terminates at the tail light assy quick disconnect connector.

Thanks for using FixYa.

Car brake light works with remote but not pedal


The alarm system usually uses the parking lights, not the brake lights so you'll have to test the brake light system. If your car did use the Brake lights absolutely,,, then your brake lights would be good & that would generally mean it's the fuse or the brake light switch.

I suggest that you check the fuse first with a 12 volt test light or multimeter, if it is good with current coming through, you'll need to test the brake light switch,, it's located just above the brake pedal, with the brakes applied you should be getting voltage at both terminals (my chart shows those wires as black/white) if so, then it must be the bulbs.

there are a few other options but this is the basic brake light system.

good luck.

LED Brake Lights diming


I had the same problem with my 2004 TL, and it was the brake light switch. It is very easy to replace. (10 min) I ordered one from Rockauto.com for only $6.95. To replace: Remove the black cover under the steering wheel, down by the fuses (held in place by rubber pins and clips - no screws) Locate the switch on the arm of the brake pedal. Unplug the switch, twist the old switch out and install the new one - it's simple!
