03 Jeep Wrangler fog lights won't turn on

I have an 03 Jeep Rubicon with only 15,000 miles, and the fog lights will not turn on. I checked both lights, and the bulbs are good and the sockets are clean. I put in another relay, but still nothing. Then, I turned on the headlights and fog lights, and checked the relay contacts for power. There was no current at any contact. The switch is part of the turn signal, and I don't know how to check that. Any ideas?

The lights need to be on low beam and then pull out on the arm that controls the lights (left of steering wheel)

There seems to be a problem on the power side. You should have at least one terminal at the relay that is hot. The switch activates the relay and transfers the power from the "live" terminal to the hot lead to the lights. Good news is you can completely disconnect fog lights and make your own harness (including a relay) and use a push button or toggle switch on the dash, just like the aftermarket add on lights use! (and it's likely cheaper and more reliable than the original setup)

Fog Lights stay on


Coincidentally, starting today, 6/22, my '04 Wrangler with 85K miles started having the same symptom. It's not the relay though. My lights will turn off if i press in on the fog light switch in the off position on the turn signal lever but when I release the pressure they come back on. I also pulled the fog light relay to shut off the lights. Unfortunately, I believe the only solution is to replace the turn signal lever.

Cannot get my Fog lights to turn off. on my 03 wrangler!


Could be the wires. If they are older, they might have burnt out or had water get into them.

Need fog light installation instructions


Stop by your local Jeep dealership and ask teh service tech to go over the schematic and wiring diagram with you.
Most Jeep service depts. are quite helpful and won't charge you for knowledge.
Then head over to NAPA and get the parts for cheap.
If you are restoring to factory specs for show car purposes, you should get the MOPAR parts right from the dealer.
Most of the time the Jeep Wranglers have the wiring already in place, you just have to know where to look for the unused plug. At least that's how it is with my 2007 JKL Rubicon.

How do you turn on the 2009 Rubicon fog lamps?


Try this: Grab the tip of the stem that controls the lights and pull in the direction as if you were going to make the stem longer.
