Dome Light Not Working

Did this "just happen" or did it ever work?

Make darn sure you have the correct bulb.......they are dual contact. Power goes up to the socket on one contact, through the bulb, and out on "yellow" which runs to door and headlight switch. This yellow is grounded by the switches to activate the bulb

I would "carefully" probe the socket and see if you have power on one contact

You can download free factory shop manuals as well as alternative aftermarket wiring diagrams at MyMopar. The diagrams in the shop manual is more complete and more accurate
