Ive changed the bulbs, bulb sockets, the brake light switch and checked the fuses. the turn signals on the front work, but none of the rear lights (turn signals, reverse lights, and brake light) come on. only the high mount brake light works. any ideas????
Read Shory and Imadrid again... great job guys. More than likely... your answers are found inside their posts.. If in question, replace all bulbs,. pry up just a little on both the socket prongs and light housing assembly (flat) tabs found inside the holes where you insert the socket with bulbs. Listen for a click sound as the turn the socket in place (All the way around). I have a 2000 Laredo and had many rear light problems. Finding some flat tabs were not make contact to the prongs, a couple of bulbs shorted out and if one bulb is bad, then both will not work and lastly the (tail light and the break lights) and the (turn signal and emergency flashers) are the same bulbs....
Problem solved and again, ... Thanks guys !
Funny thing, it's fixed but I still don't know where the rear tail light and break lights fuses are. The rear turn signal and flasher lights fuses are and the reverse light fuses are !!!!

Check BackUp Module, generally is located in the rear quarter panel (drivers side).

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 [email protected]

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

If this is an Auto trans, on the left side of the tranny just above the
tranny pan is a switch. This is the reverse light switch, replace it.
The switch screws into the side and has a 3 wire connector to it.

likely not, but change /check anyhow....If problem persists, likely you will need to change the module that controls directionals (usually under dash to the right of steering column)

This is a problem I have been
seeing more and more of lately. The brake light circuit goes through
the Lamp Outage Module (LOM). When the LOM senses a inoperative lamp,
the Vehicle Information Center (VIC) displays the data to the vehicle
operator.
Here is how to test the system (clic for zoom):
Check here for more details about the location of Lamp Outage Module (page 16).
Hope helps (remember rated this help) Good luck.
It would appear the problem is with one or more bulbs or sockets or both. As you many notice, there are no connections between the headlamps and brake lamps except the parking lamps (which share the bulbs/sockets)
When the headlamps are turned on, so does the tail lamp relay. As you can see, these bulbs/sockets are 'DUAL' filament to ground (series-parallel circuit). Just a guess here - the short is in one of the lower rear brake/parking lamp bulbs/sockets.... just a guess.
