I have a 06 jeep liberty and my left tail light goes in and out when i brake. Sometimes it will work sometime it wont.
I have a 2006 jeep liberty and im having a issue with my left tail light. When i brake it doesnt always light up, it goes in and out, sometimes it lights up sometimes it doenst. The light its self lights up when my lights are on it just doesnt get brighter like its suppose when i brake. I know its not the bulbs and im assuming its not the wiring because the whole light wouldn't work if that was the case correct? Im thinking it might be the brake switch from what i read. What do you think?
My car has 63000 miles.
My car has an automatic transmission.

Hi There,
I believe you are correct in that you have a faulty brake light switch. As you know, when you step on the brake pedal the switch closes, causing the brake light to become brighter. When the switch is bad, this may result in the brake light not working properly in response to pressing on the pedal or in some cases causing problems shifting out of park. I would suggest having a professional from YourMechanic come to your location to diagnose and replace your brake light switch.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Blown Fuse
If your lights don`t illuminate on either side and your brake light switch is good, then the next thing to check is the brake light fuse. Locate your vehicle`s fuse box, which is usually under the hood or on the kick panel inside the passenger compartment.
Common reasons for this to happen:
Sometimes when a taillight lens cracks or breaks, it can allow moisture to enter the lens and cause a short circuit, blowing the fuse. Burned Out Bulbs: In the case where only one of your rear lights appears to be out, the cause is most likely a burned out bulb.
Bad Switch: One common reason for the Parking Brake light to stay on is a failing or failed switch. This can be checked easily by jiggling the handle after it is down. If the light turns off (or turns off and then back on), the switch is the most likely culprit and will need to be replaced.
Failing Sensor
If a sensor fails, it can interrupt this complex design and cause a part to stop functioning properly. If both the headlights and parking lights fail along with the tail lights but the brake lights keep working, a sensor is likely to blame.
A blown fuse. If the bulb or socket isn`t the problem, the next check is the fuse or the light switch. Fuses for everything electrical, including your tail lights, are always found in the fuse box. They are usually located under the hood or in the cabin.
A blown fuse usually causes both lights to go out. On newer cars, the tail lamps can be fused separately and/or each bulb or shared circuit can be fused. A fuse can be blown due to other problems, so you`ll need to check more than just the fuse, but it`s the right place to start.
Low Brake Fluid: Your Parking Brake light is a multifunction device, and is designed to illuminate if the fluid level in the reservoir drops below a certain point. You may notice the light turning on or off when going around turns as the fluid level changes.
If your car or truck has one headlight not working, such as one high beam or low beam not working, one tail light working, or the daytime running lights are not working on one side, there might be a problem with the bulb or the fuse.
The most common wiring problem for taillights (brake lights) is a loose lightbulb socket. If it`s loose, the ground path is broken and the current can`t return. That means that the metal portion of the bulb isn`t making good contact with the bulb socket.

When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
ANSWER : I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.
All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.
EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.
Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
ANSWER : The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.
No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.
tail light wont work brake light will
ANSWER : You need to look at the front parking lights to see if they work with the parking lights on. Check the #11 15 amp fuse in the engine compartment fuse box to see if the fuse is good. If it is blown, then try to replace the fuse and turn on the parking lights. If the fuse blows again, then remove both rear bulbs and put in another fuse and see if the fuse blows again. The short may be in one of the bulbs you put in or one of the sockets that are shorted. There is a parking light relay in the relay module under the dash if the power does not turn on. Have a mechanic diagnose your rear lights if you need further help with this.
