Fog lights randomly turn on...'05 TJ

Post by Cowboy » Sat Jun 14, 2014 5:40 pm

I thought it was only a Friday the 13th thing, and my Jeep was masquerading as Christine for the day, but it seems to keep happening through today.

Yesterday my dash fog light indicator came on, I thought it was just a glitch, but no...the fog lights were turned on. Rotating the wand (on then back off) would get them to turn off, then they would randomly come back on again. On the way home from fishing today, they came on and I couldn't get them to turn off by fiddling with the wand.

Any idea what's causing this, or better yet a quick/easy fix?

Bad switch would be my guess, but I suck at electric stuff.

Last night they turned off when we got home and shut the ignition off. I figured they would shut off with the ignition again...but not this time. I just went out to move it so my wife could park in front of the garage when she gets back and the battery was dead. I didn't pay attention to the fog lights staying on, but sure enough they were (dim) and the dash indicator was on, even though the key was out.

I've got it on the battery charger now, and pulled the fog light fuse from the relay box under the hood.

Those switches are a pretty common problem. My wife's 05 Tj ha the exact opposite. Fogs won't work at all.

My '03 was doing the same thing, bad switch. I pulled the relay out until I got a chance to replace the switch to keep it from killing my battery. Switch replacement was pretty easy.

Isn't the switch "in" the wand?

It is on mine. I had the same problem, ran the battery down at work because the fog lights were no longer turning off with the headlights. Was going to pull the relay when I got home, but apparently it fixed itself on the way home. Cleaned the relay and stalk as well as I could anyway. Not sure if it's relevant, but when I first got the Jeep I did perform the mod where I bent a pin on the relay to enable the fog lights with the high beams on.

I may have to find the relay and see if it's stuck closed..? It doesn't make much sense to me, the fog lights haven't been used an hour in the life of my Jeep.
