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

Thanks so much for the info. We had a brake light that would go out every time we had the headlights on. Fixed in a jiff.

This just worked on both sides. I don't know how long these lights have been messed up. I also owe a thanks to my sister in law who noticed it tonight and called. Way to go Wendy A.

Help. I tried the method above so I was able to get the passenger side turn signal working again.

However, I am still having an issue. When the headlights are on the brake lights wont work. Any suggestions?

Thanks for this post was the same problem I had. I did notice a crack in the plastic around the singal ground post but put a pocket knife under the contac and bent it up a little. This did resolve my probelm.
Thanks again for this post.

Thank you for the tip... I am pretty good with tail light systems and this one had me going. No melting visible on mine but a small crack next to the ground contact..

Thanks H8tank! We had the same left brake light problem (2001 Grand Cherokee). How did you figure out that it was the ground?

Thank you Gary H; I started by replacing the brake light switch because the break lights would not come on when the head lights were on. So I did what you recommended and now the brake lights work with or without head lights on. It's a 1987 jeep Cherokee. Thanks again!

Thanks for this! The dealer and another mechanic couldn't solve the issue, and I've tried a few things as well. Too easy.:)

I couldn't get mine to work after bending the prongs, so I reattached the tail light and turned the turned the bulb all over the place until it lit up. My prongs were simply mis aligned. This might help someone with similar issues.
