89 Cherokee Fixing Cargo/Dome Light Issues
1989 Jeep Cherokee XJ Pioneer 4.0L I6 Renix AW4 NP231
It's time to fix that pesky Dome light that doesn't want to come on when you open a door. The Dome Light and Cargo Light are connected together so they should both come on at the same time. They are always fed fused positive power and are activated by a ground circuit. Each door, the hatch, and the headlight switch can ground these lights.
Order of things to check:
1. Dead Battery
2. Blown Dome Fuse
3. Blown Dome Light
4. Bad Door Jamb switch
5. Bad Cargo Switch
6. Broken Wire
