I have a 2000 Jeep Grand Cherokee. When the car is off, the driver side brake light works. When I turn the car on, the driver side brake light does not work. Has anyone else had this issue and if so how did you fix it?

This is the corrective method for your brake lights not working when your headlights are on your 2000 Jeep Cherokee
1) The cause of the problem is heat from the bulb.
2) Remove the light assembly as if you were going to change a bulb.
3) Turn the socket and remove it from the taillight assembly and set it aside(check to be sure your bulb is not burnt out).
4) Look at the opening, you will see 3 flat chrome colored contacts on the assembly.
5) Notice the one by it self at the top of the opening, that is the "ground".
6) If you look closely you will notice the plastic around the ground contact has shrunk a little bit, this caused the contact to pull away from the socket, causing the problem.
7) With a small flat head screwdriver, VERY GENTLY pry up the contact so it stays slightly upward by itself.
8) Re-insert the bulb assembly back into the housing and press your brake petal with your lights on.
9) You should be in good to go!
10) Tools: Phillips head screwdriver and a small flat head screwdriver.
11) Time : 5 minutes per light

The other option is to change the entire tail light assembly to correct your problem.

SOURCE: the tail lights are out, so the brake lights-Jeep Grand Cherokee

i have a 2002 jeep grand cherokee i had the same problem when i would apply my brakes when the headlights were on my brake lights would go out, i found that my bulbsocket was not making good contact with the socket housing, if you notice when you take off a bulb, look at the light fixture where you unscrewed your breaklight bulb you will notice 3 medal contacts-they should be silver in the socket housing and like a copper on the socket bulb, in the socket housing their should be 2 silver contacts together and 1 by itself the one that looks by itself is making bad contact with the copper one thats by itself on the bulb, what you can do for a quick fix is; get a small piece of low cage wire or a thin piece of metal like copper stick that in to the bottom or top of that metal contact--i did it through the bottom leave the wire or piece of medal sticking out enough for where it can get contact with the bulb (just a little wire is enough to make contact, now screw the bulb on and test it---it will work----i did it to mine, if you need more assistance let me know lmadrid82@yahoo.com

First, I want to say thank you for the info, you saved me money and aggravation. Second it took mea little while to figure out what contact I was looking for. So I would like to provide a little more detail to make it easier for others in the future.
This is the corrective method for your brake lights not working when your headlights are on(2000 Jeep Cherokee Larado).
1) The cause of the problem is heat from the bulb.
2) Remove the light assembly as if you were going to change a bulb.
3) Turn the socket and remove it from the taillight assembly and set it aside(check to be sure your bulb is not burnt out).

SOURCE: brake lights dont work

Check the brake light switch, it is down on the brake pedal lever, you can dis-connect the wire connector at the brake light switch and check for broken wires at the connector, and then jumper the connector with a paper clip, if the brake lights come on then replace your brake light switch.

There might be more than one switch attached to the brake light pedal lever, the brake light switch usually only has two wires going to it when there are two switches.

If there is no problem with the brake light switch then you can suspect the turn-signal switch to be at fault, as all of the running lights, turn-signals, brake lights, and hazard lights are all ran through the turn-signal switch. You can also try stepping on the brake pedal and wiggle around the turn-signal switch and see if the brake lights flicker or come on.

How to fix my right brake light and fast moving turn signal on my 2000 Jeep Grand Cherokee?


The most likely problem is two burned out light bulbs. A burned out tail/stop lamp on the right side and a burned out brake lamp on the left. If you have already replaced the bulbs, then yes, the circuit boards are the next most likely cause of the problem.

2000 Jeep Grand Cherokee, I had blinkers and flashers no brake lights, and after checking the bulbs in the light itself I dont have blinkers or flashers at all


Just no turn signals in the back now? Maybe didn't install the bulbs tight back into the asm? No brake lights...do the lights work with headlights on and just no illumination with the brake pedal depressed? Could be brake light switch.

This sounds like you have some wiring crossed. the best solution is to have a dealer check this issue. Wiring can be extremly tricky. Be forwarned though that for wiring it's usually a diagnostic check and repair. Don't be surprised if this is a costly repair.

2000 Grand Cherokee both brake lights off. Hatch brake light works. All other flashers, lights and turn signals work. What now?


You may just have 2 bulbs out. Remove the socket from the housing and check it with a test light, while having a friend step on the brake. If you have no power at either side, check all related fuses and make sure your trailer harness connector doesn't look like a green fuzzball.
