These have a problem with the sun visor wires breaking and shorting out. you can that the screws out of the sun visor where it goes into the roof and look at the wires there.
Have you tried anything else? I have also seen the wires behind the drivers seat that go up to the cargo light get shorted there. This in down near the floor.
Another thing to check is the light under the hood.
So are all the lights working now with your jumper in?
The under hood light might need the headlights on to get power. If everything is working now then you moved the wire that was shorted. I would take another look at the sun visors, Look at where the wires come out of the post on the sun visor.
The wires for the visors come out of the visor and connect to the wires on the headliner. The wiring diagram shows a switch on the light under the hood. If the switch is on then possible bulb.
Is it possible that the wire to the under hood lamp has broken and the power side is touching the body or engine?
