The dash lights do not work.

most dash lights can be dimmed or switched off check this first, then trace the wiring from the switch to the dash lights for a bad connection.

could be the bulb or door switch. I believe there is a switch to turn off the interior lights also.

If the fuse is good, check the connections for the fuse. Might have to crimp them and/or burnish them.

Short circuit near the rear hatch.

It is likely the interior lighting dimmer control switch is defective or turned off.

Dash lights are on the same fuse as the tail lights. Dash lights not working is an indication that the tail lights are not working. The first thing to check is that the tail light fuse is not blown. Most of the time replacing the tail light fuse will restore both the tail lights and the dash/interior lights. If this is not the case you may have to trace the wires and look for a broken or unplugged wire in the harness.

First thing to check: fuse(s) for the cigarette lighter/power port, which may also be the same fuse for the interior lighting that went out. Could post the location of your fuse box (most Hyundai cars have 2 - one under hood, and a second under the dash (where your power port/interior lighting fuses are most likely located)), if you could clarify which model/year/engine size Hyundai car/truck is giving you problems.

check the fuse box under the hood for loose or blown fuses.

I would think that the wires from the RCW (rock climbing wall) that control the running lights are wired to the interior dash lights of the van, and a fuse blew, killing the above mentioned lights. Check the fuse block for a bad fuse, probably labeled inst lights or inst lgt. Did you make the trip there in daylight, and trip home at night? The fuse for the dash lights couldn't handle the extra drain of the RCW running lights.

Check the fuse under the dash or in the glove box!
