There is 2 screws located on the side when you open your tail gate by the tail light. remove these 2 screws and pull the tail light out and disconnect the wire connector. Hope this helps.

Best of luck

2000 grand cherokee no rear park light when the park light come on no brake

These Jeeps are notorious for the retainers breaking that hold the circuit board type wiring against the bulb contacts. With my 2000 Grand Cherokee, the brake lights would work when the headlight/tail lights were off. If the lights were on, the rear lights would go out altogether when I pressed the brakes. The easist fix would be replacing the tail light assemblies, but these are not cheap. My fix was to open up the inside cover of the tail light housing and use machine screws in each of the locations that the plastic tabs hold the retainer against the light housing.
