SOURCE: I have a 1999 Jeep Grand Cherokee Laredo - One Brake Light
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

did you try to replace the bulb in the back normally when it blinks fast like that its just the bulb and its doulbe film thats why the brake and blinker dont work
SOURCE: Tail lights work, but not one brake light when braking at night.
2001 jeep grand cherokee left brake does not work period. I replaced bulb to no avail. the entire tail lamp assembly looked brown as though it heated up. However, the tail light, signal light and back-up lights still work. Please help.

Hi .. First I would remove the lamps, and try the brakes, then try again with the wiring harness disconnected from the housing, to see if you can isolate the problem to the lamps, the housing, or the wiring. If it is the wiring , then you will have to trace the harness back toward the front of the car looking for any place where the insulation on the wire has been damaged .

The problem is that the tail lights, light bulbs get too hot and melt the plastic where the bulb socket goes into the lens assembly. On the lens assembly you will see one to three metal tabs where the socket fits into. Lift up the tab a little bit with a screw driver and place a small amount of either metal or plastic underneath the tab so it will get a good connection. It will fix the problem.
