Doomlight stays on or will not turn on when door opens

The first thing to check on these jeeps is the wiring coming into the door. open the door and check the hinge area, in the middle you will see a rubber boot. inside the boot are the wires that feed the door. before you check that try to open the passenger side door to see if the dome light comes on when that door is opened. if light comes on with that door then check wires on driver door. if door light does not tturn on with pass door then you have module problems. if dome light operates with other door and wiring is good then you will have a bad door switch, this switch is the dome light switch, it will be on the door latch or on the pillar. good day.

You have a dome light/door ajar switch that is defective, the switch is a tiny micro switch attached to the door latch assembly inside the door, to replace it requires the door panel be removed.
