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.

99 jeep cherokee, horn sounds when locking with remote. Checked all door switchs and seem to be working fine?? any ideas?


Its supposed to beep once when the doors are locked, giving an audible confirmation that your anti theft is armed. The parking lights will most likely flash as well to give a visual confirmation. If you have the over head computer in this model the horn confirmation option can be turned on or off in the normal settings menu.
