Horn on 97 jeep wrangler doesnt work or have power.

SOURCE: 05 Jeep Wrangler High Beams Work, Low Beams dont

There are no relays for the headlights. Your problem could be from the headlight switch. You would have to check and see if you have power coming out of the switch on the low beam side. Check with a test light.

Try a couple things if you haven't tried already.

First try replacing the bulbs (sometimes the most obvious answer is the right one, and not meant to offend you).

Then, try replacing the headlight relay (found in the fuse box and looks like a small black cube that plugs in similar to a fuse with some extra prongs).

Then, try replacing the headlight switch.

Finally, while inspecting the headlight switch, make sure the wires are connected and not broken, worn out, or corroded. Same thing with the wires connecting the headlights.

Let me know if this helped you out.

You have two locations for the fuse box. One is either under the hood or behind the glove box. I would pull apart the glove box and take a look.

If you are facing the front of the jeep. It is on your left, on the fender well. Yes, you do have a fuse under the dash. The fuse panel should be marked on what fuse is it.
