Check your fuses. They are usually located in the glove box. They are easy to change and only cost about $5 for a box. Check your manual to see which fuse is for the lights, if the medal bar is broken you need a new fuse.

I have a 1977 Chevy Impale,the brake light wan't work and when turn on the turn signal to right the left come on also.Do you know the problem.

check the brake light switch,on the brake pedal. it may be out of adjustment or just plain faulty.

I just recently had this fixed on my 2000 Pontiac Grand Prix. The brakes lights were out on both sides but worked in the rear glass. Ended up being the turn signal switch which for my car was a $350 part and with labor was a total of $507. Good Luck!

You may have a short in your wireing. Also your wires might not be hooked up to your lights.check your plugs and if they are good you might want to take it in to a shop.

it is common for your earth wire/s in the brake light plastic housing to have a bad connection and can be corrected by tightening the screw that fixes it to the housing.(located near where the bulb/s fit)

On my LHS, it appears that the switch that connects to the brake pedal went out. Hence, all of the brake lights do not work. Something to check out as well in doing your diagnostics.

Change them. If you do not know how, take them to a mechanic. It can be as simple as a fuse. If not, check brake light switch. The switch can be attached to the pedal under the dash or it can be attached to the hydraulic brake line, depending on your vehicle. It can also be a grounding problem, meaning that the ground wire to the tail lights can be broken, unplugged or there can be a bad connection to vehicle ground. It can also be the turn signal switch or wires leading to the turn signal swith.

your brake lights and tail lights are on different circuits... tail lights are connected to the lighting circuit..eg..headlights, parking lamps, dashboard illumination. If none of these others work also-1st check the lighting fuse, if it is just your tail lamps check globes, wiring and maybe a separate fuse within the wiring harness. It may also be that you have a bad connection, either power wire or earth to your light cluster at the rear of the car.

Most likely a fuse but could be a bulb or other issues. Here's a good list of things to check:

Bulb Troubleshooting (check in this order):

· Check Fuses

· Check Bulbs

· Check Relay(s)

· Check Light Switch(es)

· Check license plate light bulb and wiring

· Check trailer hitch wiring harness

· Check all wiring harnesses and wire

Most likely its the fuse or a burnt bulb breaking the circuit. Sometimes the license plate and/or the trailer hitch is wired into other circuits and can cause issues in other areas. Sometimes its wires grounding out somewhere on the vehicle. See sources and related links below for bulb information. See owner's manual for location and identification of fuses as well as for bulb replacement procedures.

If it is just one brake light, the chances are good that it is the bulb. Bulbs are cheap.

They are two separate circuits. Check the bulbs and fuses first.

Bulbs are out, bad fuse, or corroded connections. Also could be switch on brake pedal, but most likely is bulb or fuse. If bulb, see sources and related links below.

How do you replace right rear brake light on 1999 Ford Explorer when turn signals and parking lights work.?

you have to replace the parking light bold because is the same as the brake light so just replace the light bold I think is the middle one between turning light and backing light. you have to replace the parking light bold because is the same as the brake light so just replace the light bold I think is the middle one between turning light and backing light.


How do you fix only one brake working?

There are several things I would need to know to answer correctly:What kind of vehicleWhat yearWhat type of brakesThe fact that one brake does work means there is an underlying problem with the rest that needs to be repaired.Usually on a car one brake working means that the other three have seized hydraulic systems in each brake and require the replacement of the cylinders or Calipers.


What should you do if the brake lights on your 94 Geo Prizm do not work?

If neither one is working, the first thing to check is your fuse. If the fuse is okay, replace the bulbs and if that doesn't work, it's probably the brake light switch. The switch is the least likely culprit though because they rarely go bad.


What does it mean when my brake light stays on?

It probably means that there is a problem with the electrical connection between the brake ligts and the brake pad and so it does not light when one brakes. Another possibility is that there could be a real serious defect in the braking system e.g. the brake fluid tubes.AnswerIt means a lot of things, but the most common and simplest is that one of the brake light bulbs burned out. Honda puts two in each brake light so you don't get rear-ended on the freeway or pulled over by the cops before you can get to the auto parts store, but check your brake lights by pulling each bulb, inspecting it and cleaning the socket. It could also mean the brake fluid is low. The most common reason for this is that the brake fluid in the reservoir goes down as your brake pads wear our. Warn pads often result in low fluid and a brake warning light. Check your fluid level. If its low don't fill it. First, check your brake pads front and rear to see if they are worn out. If you fill the reservoir and then replace the pads, you will spill fluid out of the reservoir when you push the pistons back in the calipers.The other most common brake light indication is if the emergency (parking) brake is engaged. Check to make sure it is released.I have to disagree with the second answer. Normal brake wear will NOT cause a lower fluid level. The brake indicator on usually always means low fluid in the brake system. Blown light bulbs in the brake circuit will NOT cause a brake light to come on. It is only something directly related to the brake system. Brake Fluid is the monitored component in the brake system. It also will give an ABS light with LOW FLUID,,,,possibly indicating a leak.


How do you wire up a brake light switch on a 1965 Chevy II?

There should be only two wire connections on the stop light switch. You need to put a constant 12v supply to one side of the switch and the light wire itself to the other side. The switch then needs to be adjusted so that the brake pedal holds the switch in to keep the lights off. When the pedal is depressed the lights will go on. If they stay on all the time, re-adjust the brake switch.

What is the problem if you have tail lights but only one brake light?

The tail light/brake light bulb has two filaments. If one of the filaments is broken, you will get either only tail lights, or brake lights. If a new bulb doesn't work, then you have a broken wire or bad connection in your plug-in.


Why is third brake light the only one working on a 2007 landrover lr3?

What would make your brake lights not work?

The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.


Why does one brake light work and the other brake light does not work?

One possibility is, on multi-light tail light assemblies, is a burned out bulb. Some cars have separate light bulbs for tail, brake, turn, and backup lights The other possibility is an electrical short in the wiring. Somewhere in the miles of wires, two wires have crossed or the insulation has worn off and is shorting to the chassis. The only cure is to trace out each individual wire with a voltage meter.

Why would the brake lights on a 96 Altima not stay on when the headlights are on and only work when using the brakes?

??? Your brakelights are only supposed to come on when using the brakes. Do you mean that your TAIL LIGHTS don't work? Hey Jose==Your TAIL lights may have a fuse blown or something could be wrong with the head light switch. You just have to check it out. GoodluckJoe The tail light bulb has two filaments in it. One for the tail light and one for the brake light. The brake light part is still connected but the one for the tail light is broken. All of this is inside the bulb. Happens all the time. Just need to replace the tail light bulb.


Can you tap a wire into the left brake light wire and run the new wire under the car and tap into the right brake light wire to make the right brake light work?

Yes I actually did it yesterday on my land rover I could not get my tail light to come on only my brake light. Use a decent wire like one side of a good speaker wire will do it's what I used. Tie it into the "hot" or positive wire of a working light into the positive of the non working. Make sure the lights you are tieing together do the same job i.e. Q brake light to a brake light. If that doesn't work check your ground. Also this only helps if the wiring is bad that is sending the light the signal if the fixture is bad you will have to replace it.


Why might the third brake light not work if the others do?

Check the switch. It has a different one than the regular brake lights. the light bulb could possibly be blown
