No brake lights
I have a problem with my 2002 Grand Cherokee. It has no brake lights that work in the tail light assemblies. The brake light above the rear window does work ever time I put on the brake, so that tells me that the brake light switch must be working, Anybody have an idea what would cause neither of my brake lights to work. Replaced both bulbs and still no brake lights.
Thanks in advance

Probably a fuse, or a short somewhere. Check your fuse diagrams and check to make sure you don't have one popped. If i remember correctly, (I may be, probably am wrong) the light above the rear window is on a different fuse than the bottom two.

there is a circuit board in one of the rear taillight assemblies that will sometimes fail and cause very crazy behavior

Well Guys
Fuses are OK and I can't seem to get to the circuit board the tail light assembly is glued together. I do have the 12v's from the brake switch to both my tail light assemblies, both stop lights work on my boat trailer when plugged up. Any other ideas.
Thanks

See if you can access the power wire running to the tail light. Use a test light and have someone hit the brakes. If it lights up then it could just be the ground or light housing. My dads van had the same problem power to the housing but not to the bulb. Replaced the housing and brake lights worked.
Chase it down, thats wiring. I normally start from the fuse block to the problem and chase chase chase. hahaha

That is what I was talking about, I used a meter and when somebody steps on the brake pedal I have 12 V to both pig tail plugs that plug into the tail light assembly which is the brake light wire because when they let off my volts drop to 0. I tried this several times on each side. Looks like I am going to have to purchase two new tail light assemblies and go from there! Any other fixes other then purchasing new assemblies?
Thanks

ts thanks, I think that is my problem cause one quit first and a about 2 months later the other one quit. I tried to take one of the tail light assemblies apart, the back on them have clips but they have epoxied the back on it. I guess this is a way to make sure you have to purchase a whole new assembly. You can not get it apart without messing it up beyond repair. Looks like I will be ordering 2 new assemblies.
Thanks again

I have changed the sockets; didn't work.
I have changed the fuses; didn't work.
I have changed the connectors in the tail light; didn't work.
I have changed the brake light switch and adjusted adjusted properly;didnt work.

Old fart with a wrench
Check the bulb holders, the part that actually holds the bulbs. Sometimes they get hot and melt enough to release pressure on the bulbs enough to break contact. Try switching the reverse light holders to the brake lights and see if they work. Melted plastic seems to be a common problem with WJ tail-lights, especially if you spend a lot of time in traffic with your foot on the brake. All the bulbs and holders are the same, the difference is in the wiring in the housings.

If one side failed and shortly afterward the other side failed, it is likely the boards. Same age, same heat etc. After monkeying around with mine for way too long to keep them working, I bought a set from EBAY for cheap. It made my wife happy and allowed the local law enforcement more time to pursue real crime.
