Where is the headlight relay and fuse on a 99 wrangler

uder right side of dash behide glovebox

this could be linked to a fuse or relay. if your headlights work normally while driving, then the relay may have gone bad.

-Check "headLight fuse"
-Check connector at the headlight.
-Check the bulb. (It could burn out)

You have separate fuses for high/low beams. Check that.

Could also be a fuse or relay problem.
You'll need to find out if the coil has voltage and if the pick-up stator in the distributor is sending a signal to the computer.
Might want to check the computer for trouble codes too.

Look inside the engine compartment for a black box.
Inside will be a bank of small electronic relays.
Look for the one for headlights ,should cost you anywhere from $10.00 to 22.00
The same box contains air conditioner relay,charging relay,air bag,ect...

alot of vehicles have a seperate fuse and/or relay for the high and low beams. if you can't find a problem there it could be the swich itself.

I would check your headlight relay switch that is located in your steering colum

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.

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.
