Light issues Yes i have a 2004 grand cherokee that is having some back light issues. for some reason my back brake lights and running lights are not working. The front head lights and everything work as well as the blinkers for the back and reverse lights. its just the running lights and brake lights in the back that are not working. I have already changed the bulbs and hub, checked all fuses that could be found. and all were good. as well as changed the brake switch at the brake pedel. what could the issue be

SOURCE: BRAKE LIGHTS DO NOT COME

it could be related the connector cables thats bridging your lights and your brakes????

SOURCE: 1993 jeep grand cherokee limited no running lights/tail lights.

Id look at the headlight switch and do some voltage tests to see whats coming out of there. Pay close attention to any wires which look like someone was in there already.People can mess stuff up faster and better than the vehicle can by itself!

Check the brake light switch, it is down on the brake pedal lever, you can dis-connect the wire connector at the brake light switch and check for broken wires at the connector, and then jumper the connector with a paper clip, if the brake lights come on then replace your brake light switch.

There might be more than one switch attached to the brake light pedal lever, the brake light switch usually only has two wires going to it when there are two switches.

If there is no problem with the brake light switch then you can suspect the turn-signal switch to be at fault, as all of the running lights, turn-signals, brake lights, and hazard lights are all ran through the turn-signal switch. You can also try stepping on the brake pedal and wiggle around the turn-signal switch and see if the brake lights flicker or come on.
