I have this same issue going on. I called the Jeep dealer, and he said it isn't a common problem, although I was behind another Grand Cherokee 2 nights ago that this same thing was happening, except both of his brake lights went out when he pressed the brake. He said the circuit board might be burned out (if the outlet looked brown, which it doesn't), and if that is the case, you would have to replace the entire taillamp!
My brake light works when the headlights aren't on, but when I turn the headlights on, is when the brake light goes out when I press the brake. Mine is a 2001 also. Sounds like something is going on here. only does

I'm having the same problem with my 2001. The guy I bought it from says it's just because of the wrong bulb was put in, but it sounds more like a PCB or harness problem.

I have the same problem with my Jeep. Sometimes when I move the light bulb arund it works sometimes it dosen't. So try that and if that happens there is just a bad connection with peice that the balb goes into or just migt have to buy a new back tailamp.

I'm having same issue on my 2000. Both mine don't work when the lights are on and another thing it does is the third brake in the middle is on all the time (Dim). only when lights are on..that light should only come on when I step on the brake.

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).
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

Joel and Jeff,

Thank you for your posts. Just saved me a great deal of heartache. I had already ordered a few upgrade light kits to replace my oxidized lenses on the headlights, but my passenger side tail light died last night creating similar problems to those described herein. Took it in to get looked at and they could not fix it. Said I needed a new light assembly and that they could get one in a couple of days. I came home and Googled the issue and found this thread. Joel's post pointed to a great resource. Jeff's post is in that same resource and here. I followed the steps and found that my mechanic had put the replacement bulb into the bulb holder correctly, but had installed the bulb holder into the light assembly upside down so the contacts would not line up properly.

Long story shortened...I put the bulb holder in the correct way and everything is working fine now. Still upgrading to the new lights, because the socket with the burnt out bulb has gone before and is a bit charred looking.

Thanks guys for your great posts.

I am going to try the fixes in this thread as well to see if it helps with my problem. It is similar to the main problem described, but slightly different as well. In my scenario ( I have heard of 2 other cases so far)On my 2000 GC Laredo, I have the upper brake light, but the other brake lights are not working. My tail lights and the turn signals work fine. I checked the fuses both under the dash and under the hood just to be thorough and found no problems. Thank you for your posts, and I help that your help cures my problem as well.

My 2001 Jeep Grand Cherokee is doing the same thing. Replacing all the bulbs did not work. I connected the right light fixture (it works fine)to left side and I have the same problem - The brake light works fine when the lights are off; when the lights are turned on the the lamp goes off when the brakes are applied. This seems to suggest a short although there is nothing obvious in the wiring that I can see with the light fixture removed. Any help is appreciated. Thanks.

Same exact issue on my 2001 Jeep. Works fine with headlights off but left tail light goes out with headlights on and brakes applied. I took the twist on housing and bulb from the right side and same problem so seems it has to do with the assembly or wiring.

I have a 2000 Jeep Grand Cherokee and it seems like everyday while traveling through ATL traffic some one tells me that my brake lights are out. I have a friend that has a 2000 Jeep Grand Cherokee as well, and we have all of the same issues, including brake light problems. She replaced the bulbs in her jeep and it worked okay for about 2 weeks, then they went back out. She contacted the dealer and they said they would have to replace the entire tail light. I think it is amazing that we all have the same issue, but Chrysler says there is no problem!!!!!!

JEFF from Cape Coral FL has the right answer!! Pry UP one of the three Chrome Flat Contacts and you are in business. I spent time sanding these contacts and didn't realized how much it was press down. Like most of you, my prior fixes only lasted for awhile. JEFF's fix though works as discribed. I'm sure the contact will go back down after awhile but at least I know how to fix it. THANKS!!!

Jeff,

I want to say thank you for the write up/fix. It worked like a charm. I saw the other writeup of the fix, but I didn't work up enough heart to do it (for fear of screwing it up) until I saw your numbered run-down.

The fix was easy, and while it'll probably happen again at some point -- at least I know how to fix it. And now I can drive at night with no fear of getting a ticket. Not to mention the money and annoyance I saved myself from, not having to goto the dealership and get new light housings.

Thanks again!
