If you have no brake lights, and you've checked the fuses and the bulbs then, the problem is likely a the brake light switch on the brake pedal arm. The switch needs to be adjusted or replaced.
Hope this helps.

Where do i find the lamp outage module in a 2000 grand cherokee


did you scan the PCM first.
rear lights dead, not dead dash brake warning light.

check all fuses first?
the fuse is in the cab or under hood
so lets find out where, i open FSM book, and look at schematic
brake lamps
the fuse is in JB box. cab fuse box.
its marked clearly as. Fuse F23 Brakes.
the brake switch is on the brake pedal.
if the fuse is good, 12vdc on both sides.at all times.
then the brake switch is open
if its output is 0v brakes pressed.
if the output is 12v then the switch is good, and the wire
are bad, to the rear.
or both lamps burned out or both sockets bad or wires cut
from trailer hitch hacks,.

I have a 95 jeep grand cherokee and the lo beams dont work. highbeams are fine, replaced lights, switch is working, and all fuses are fine. is there anything else i should check?


There may be a lamp outage module, and you may have low and high beam relays in one of the fuse boxes in the engine compartment.
Check your owners manual if you have one.

How to fix my right brake light and fast moving turn signal on my 2000 Jeep Grand Cherokee?


The most likely problem is two burned out light bulbs. A burned out tail/stop lamp on the right side and a burned out brake lamp on the left. If you have already replaced the bulbs, then yes, the circuit boards are the next most likely cause of the problem.

The Rear Lamp Failure light comes on, and Ii have no been able to locate where this is located. I do not have an owners manual. I have checked the tail lights, brake lights, even the tag lights, and I am...


Nice SUV, I have the same with 5.2L V8 Limited!!!

Are you sure that there are no lights out?pay attention to the third brake light because it has 3 bulbs and if one is outit will give you that message.also make sure that all of the bulbs are the right ones.

I used to get the "Rear Lamp Failure" message on my '93 Limited after the lights were on for a few minutes... it went away when I changed the rear bulbs to the same brand. The Lamp Outage Module (located in the LR quarter panel, near the fuel filler) is looking for differences in current flow between the left and right side bulbs.

You probably need a new lamp outage module...
CIRCUIT OPERATION
The Lamp Outage Module (LOM) determines if a rear lighting lamp is not operating. When the ignition switch is in the START or RUN position, circuit A1 from fuse 8 in the Power Distribution Center (PDC) connects to circuit A21. Circuit A21 feeds circuit F87 through fuse 5 in the junction block. Circuits F87 feeds the LOM.
- Circuit G46 from the LOM connects to the Vehicle Information Center (VIC) . When the LOM senses a inoperative lamp, the VIC displays the data to the vehicle operator.
- Circuit L90 which feeds the tail lamps and side marker lamps, connects to the LOM. From the LOM, circuit L90 continues to the license plate lamps. Circuits L21 and L22 from the LOM power the tail lamps and side marker lamps.
- Circuit L50 from the stop lamp switch connects to the LOM. From the LOM, circuits L73 and L74 power the stop lamps and circuit L87 powers the Center High Mounted Stop Lamps (CHMSL) . Circuit Z1 grounds the LOM.


If you need tha owners and repair manual about your ZJ Grand Cherokee, just keep in touch and send me one comment.

Hope this helps (remember to rate this answer).

Where do i find a fuse box diagram for a 1994 Grand Cherokee Laredo?


There are 2 fuse blocks. The Power Distribution Center is under the hood along the passenger side fender and has fuses and relays in it. The other is on the passenger side of the dash and has fuses and circuit breakers.

1996 Jeep Grand Cherokee Laredo - message center says "Rear lamps not working" - checked the fuse and bulbs, they're all fine. Replaced the brake light switch under the steering column. Any other ideas?


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.

94 Jeep Grand Cherokee Laredo: No power to left tail light


Traced the problem to the Lamp Outage Module located in the rear left quarter access panel behind the spare tire. Arcing had occurred on the left taillight line. Fortunately this part is readily available at your local Jeep recovery yard (none available in the U.S. from dealers). Recommend J& W Auto Wreckers in Antelope, CA (web site available). Massive number of Jeeps and fair prices. If you don't want to replace the LOM then you can join the two connectors that go into the LOM (LOM is optional) but you'll always show a lamp failure on your console.
