Brake lights issues, 94 Wrangler YJ Sahara

My tail break lights and turn signals work fine until I turn on my lights on. Once I turn the lights on nothing in the back works, however if I turn my hazard lights on, brake lights and hazard lights work in the back. Front lights work well. Any ideas what to check?

Go through all the grounds for the lights. Headlight grounds on the side of the radiator, tail lights ground through the tail light assembly mounting screws. Clean them and make sure they are all secure.

I had a similar issue with my 94. When I turned the head lights on the wipers came on too. It was the grownd wire behind the headlights. I unscrewed them, cleaned and re secured the ground.

I did grounds on headlights but could not figure out the tail lights. Previous owner put the tail light guards on it. NOt sure how to get in.

If you can see the 4 Phillips head screws (you should be able to see them)on the face of the lites, remove them. This will allow you to remove the lens. Once that is off you will see 3 bolts holding the housing onto the body. Remove those and the guard will come off. If you reach up into the corner of the body from below you will find the connector in the wire harness that allows you to remove the whole thing. Make sure hat he ground wire connection inside the lite housing is good and secure.

Check the wide pigtail under the steering column. Make sure all the pins on the inside of it are connecting properly. It is the pigtail that is clipped into the side of the steering column under the dash.

I would clean the grounds and mating surface of the tails and also try them without the tail light guards on.

I'm new

I got it. It was one screw in the left tail light which was controlling the whole thing. Was a little rusted. Once I cleaned it everything worked fine. Thanks for your help, guys

Can't believe the whole tail comes down to one screw, but what the hack

Thanks for posting the fix. You HAVE to have good grounds or all kinds of weird things can happen.
