This problem is very common on the WJ grand Cherokees on mine i spent about an hour farting around "fault finding" (evey where you tested with a meter was fine). Put it back together and it wouldn't work.What I found it to be was an earth fault in the TAILLIGHT ASSEMBLY. I think this is caused by too much heat distorting the base where the lamp holder twists in. I used the soldering iron (Soldering Bolt)and put a dab of solder on the little brass terminals to build up the height a bit (i have since read you can prise them up a little with a small screwdriver) Just remember if using the pry method don't be heavy handed.This fixed the problem on mine and has been good ever since.What i have also done since is replace the bulbs with RED LED cluster bulbs which i purchased on eBay (they are supposed to last for about a Zillion hours but run much cooler because they draw next to no power. The ones i purchased were 36 led 3157 wedge type to suit a 2000 WJ. You can't see any difference when operating.

Where are all the brake light grounds on 1990 sundance when the headlights are off then brake lights are fine but when u turn headlights on then the brake lights don't work except the cyclops lights.?
You probably have a loose wire connection in the brake light sockets. Insert a nail or probe tip into the back of the light socket where the wires are inserted and test the brake lights. (The socket can appear perfectly normal and the wires may even seem well attached.)
Please 1999 jeep grand Cherokee why does your right brake light turn off when headlights are on?
This will happen if the ground terminal for the brakelight bulb is connected to the power side by accident. If you have a 3 wire socket or light assembly with GROUND, TAIL, and BRAKE wires two of them are wired incorrectly. When the headlights are off the brake light is finding ground thru the filaments of the headlights. Since the headlights have much heavier filaments, they provide a good ground for weaker brake light. When power is on the headlights the brake light will have power on both sides, so no current flows and it goes out.
