If the brake light switch is bad, both brake lights would be out, so don't change it. Check the brake light socket to see if there is any corrosion inside, which is usually the problem. Use a piece of sandpaper folded over and push back and forth with a small screwdriver to clean up contact in socket. To prevent corrosion in the future, pick up some dielectric grease at any parts store, and place a bit in the socket. If corrosion isn't the problem, you need to check the socket with a voltage meter to see if there is power to the socket when brakes are applied. If not, you will have to trace wires back to find where the problem is.

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!

How do I replace my brake light fuse?


The break light have a fuse in the fuse box. If this blows then both break lights will go out. Its usually under the hood in the fuse box or its in the panel on the right or left inside where the front doors close. Some cars have a fuse box under the steering column. If this is not the problem then it may be a break light switch. These are located just up the break petal. Its a switch that gets released when the break is pushed with your foot.

Break lights dont work, I replace the lights how do you replace the break fuse what should I look for?


Bulbs are just like a fuse to for they blow out like a fuse. You have a brake light switch mounted near the brake pedal. Check that switch out with a OHM meter. Just unplug the switch and feed the Ohm meters contacts into the switch. Then push the brake pedal down to see if it completes the circuit. If a OL reading is showing at all times the switch is bad and needs to be replaced

What do the relays and fuses look like under the hook of a 96 s 10 blazer. Someone said to check theses and how do you. My brake lights dont work and the 10A fuse under the dash is good and i replaced the...


Did you check or replace the brake light bulbs?
It is more common to have burnt bulbs than a bad brake light switch or blown fuse.
Do you have orange signal lights and red brake lights at the rear?
Then the signal light switch will not affect the brake lights.....but....
If they are all red and you use the same bulbs for brake and signal....the brake light wiring goes through the signal light switch and could be affected there.
First....check for power getting to the brake light switch......and leaving it with a test light.......then go to the rear....pull a light assembly and check for power getting to the bulbs.no power? follow the wiring back to the switch looking for a bad connection.
The fuses and relays under the hood are usually in a black plastic box labeled fuses and or relays.

Fuse for trailer right turn signal and brake blows intermittently


abad ground on that tail light unit could affect current load when turn and stop are used simultaneously. Although one side only is affected make sure of good grnd between trailer and tow vehicle. focust on the tail light unit in question. Replace the bulb. though rare, bulbs have been known to be the problem. If the bulb is breaking filiments ck the filiment orientation. filiments last longer in vertical orientation, where horizontal permits vibration to break the heated filiment when brake is applied.. good luck and let me know if This helped or not.

Left and right brake light doesn't work but center lights does


check behind the brake peadle for a little button that pushes in and out when the peadle is pressed(this is your brake light switch) some cars have more than one of theese. manualy let the button out if the light works the switch is good if it does not disconect the harness from the switch and take a small piece of wire and jump the two prongs on the harness if the brake lights come on then you need a brake light switch. if this doesnt work check for power at the switch. if no power you have a bad fuse if there is power and you already jumped the wires to the switch then you have a broken wire between the switch and the tail lights.

Malfunctioning brake lights.


Most likely a short in your break line. You might also check the brake switch, but I would think if the break switch was going, it you wouldn't even have the third lite working...
