Chevrolet Repair: 91 chevy truck interior lights, chevy s10, s10 truck

Question
the interior lights dont work, nor does the cig lighter, in my sons 91 chevy s10 truck.
i've changed the fuse for dom lights.
what else should i check?

Answer
Hi Donnie,
I assume you checked the bulb.
Make sure the dome light override at the headlight switch doesn't have it turned off.
Then check for power at the light socket. if there is power there, then the door switch may be disconnected.
The cig lighter may be a different fuse, and may only work with the key on.
