Question about 1999 Jeep Grand Cherokee
The tail lights and brake lights do not work at all, yet the turn signals work. what could cause that and how can i fix it?
You will have to change out the actual socket that the bulbs plug in to. I had one of my brake lights go out recently and replaced it with a new bulb, just for it to burn out again and not come on. I purchased the whole light assembly (plug that goes into the actual rear light cover with the bulb snapped into it). It only costs around $13.00 to replace each socket. The Jeep dealership stated that all Grand Cherokee's have a problem with shorting out the light socket plugs. Take your bulbs out of your tail light assembly and see if the socket plug is burnt a little. Mine was, and once I replaced the whole piece, my lights starting working again.

Check the relays associated with the tail lights, I believe that the tail light relay and the turn signal relay are two different entities. Hopefully that helps.

i have a 2002 jeep grand cherokee i had the same problem when i would apply my brakes when the headlights were on my brake lights would go out, i found that my bulbsocket was not making good contact with the socket housing, if you notice when you take off a bulb, look at the light fixture where you unscrewed your breaklight bulb you will notice 3 medal contacts-they should be silver in the socket housing and like a copper on the socket bulb, in the socket housing their should be 2 silver contacts together and 1 by itself the one that looks by itself is making bad contact with the copper one thats by itself on the bulb, what you can do for a quick fix is; get a small piece of low cage wire or a thin piece of metal like copper stick that in to the bottom or top of that metal contact--i did it through the bottom leave the wire or piece of medal sticking out enough for where it can get contact with the bulb (just a little wire is enough to make contact, now screw the bulb on and test it---it will work----i did it to mine, if you need more assistance let me know firstname.lastname@example.org
