No interior lights

[T Lipscomb]

Hey guys! Another question. I have no interior lights. The lights don’t work with the switch or the doors. The bulbs are good. The front ones won’t even come on with the switch on the actual lights but the back ones do. The cargo light works like it should. Any ideas?

Blown fuse or bad switch or dimmer likely.
Year / model / engine /...?

03, 4.0. I’ve checked fuses. Can’t find one blown. I initially thought maybe the dimmer switch but it works the cargo lights on the back.

The dimmer wheel commonly gets burned out. Believe the cargo lamp circuit does not run thru the dimmer resistor, but only thru an On\Off switch on the same assembly.
