Lost all Lights at once

I looked for a post with similar issues but came up short. So forgive me if there is a thread on this already.

Working on my 88 GW when all of a sudden every light on the vehicle went dark. Power windows, locks, wipers, and mirrors all still work. The headlights, tail lights, markers, dome, and factory fog and stopped. I hate to throw parts at it but my gut says headlight switch. Anyone come across an issue like this before?

thanks

Fusible link or power spike blew them all

Sounds like you lost the headlight switch or a fuse. I DOUBT THAT IS A LINK.

I kinda thought the same. But one thing that has me confused, would the switch control tail lights as well?

WILL THE HEADLIGHT SWITCH CONTROL THE TAILIGHTS??? ABSOLUTELY.

Sorry I meant brake lights. I know it does tail

Nope it doesn't

HMM
You might want to check the plugs on the steering column. I forgot the dimmer is on the column on that one.

Look at the wiring connector to the light switch. I've had the hot lead get hot enough
to melt it's way loose from the connector.

Thank you all for the tips. I hope to get out there this weekend and dive into it.

I had a very similar issue on my 89 wagoneer. Headlights, tail lights, blinkers, side markers, radio, dash lights, courtesy lights all stopped. It was the fuse-able link on the starter/ignition relay that is in the engine compartment. The relay is bolted to the passengers side wheel well very close to the battery. In fact a battery cable runs to it. From there check all the wires for burn or scorches.

I replaced the green fusible link and all was restored. Good luck

You do realize this was posted 3 years ago?

Yes...Guess i got a bit bored at work over the holidays!

Also, an answer is an answer. Not a huge Wagoneer community so I might as well contribute if it helps someone in the future. The internet is forever!
