All lights on the dash board is out

Bulbs are burned out.

There should be a dimmer switch to control dash lights. It have have dirt on the contacts, so twist it back and forth a few times.

Check your fuses first, park lights, I think. Pull the light switch to first click and check if your front park lights are on. If no lights are on, the headlight switch is probably bad. If the fronts work, but no tail lights or dash lights, the problem is probably a wiring problem under the dash. The same wire to the rear tail lights is usually with a splice to the dash illumination lights.

bad alternator, bad battery?

Often times the tail lights and dash lights are powered by the same fuse. The reason for this was so you would know that your tail lights weren't working if you didn't have any dash lights. I would look for a fuse that says "Tail" or "Courtesy". Your owners manual should have an illustration of the fuse panel and what circuits they power. Good luck, hope this helps!

you have to check all fuses with a test light both fuse boxes under hood and under dash... if good next to look for is the light switch itself... has any radio work been done to the lately... if so alot of times hooked up wrong will blow park fuse as one of the wires to radio is the park voltage to tell radio to dim down some

have you tryed disconect the battery for 30 sec then reconeck,I had same problem on my 2000 doge caravan and that fix it for me....hope it works for you

Dash lights were falsing ? I assume you mean pulsing .
driving lights come on ? daytime running lights or park lamps ,does the vehicle have daytime running lamps . Daytime running lamps module .
Daytime Running Lamps (DRL) Module (Headlamp Auto Control Module)
Mounted behind the radio and the HVAC control, left of the instrument panel compartment.

this could be a faulty light switch try swapping it with another switch

I have a 1997 jeep wrangler with the same problem and it started when I replaced the stock radio,with an after market one. The dash/parking lights are grounded to the stock radio,so if you can find a good body ground that should fix your problem. good luck.
