Fog lights won’t turn off (3 Viewers)

[M1911]

My 2013 is turned off — the ignition is off, but the fog lights are still on. Turning the fog lights on and off via the headlight switch doesn’t change anything. I’ve tried turning the headlights on and off, but no change. When I disconnected the battery, the fog lights went off, but they came back on as soon as I reconnected the battery.

Any ideas?

I would check or suspect the fog light relay in the engine bay fuse panel. The relay may have been failed in the on position.

What fog lights are you running and did you make any further mods?

Here's a diagram for the early model year 200s. May be slightly different for a 2013?

Have any rain or washed the truck recently?

Check the connectors in the A-pillar on the driver's side. If your sunroof drains are / were clogged and flooded the a-pillar, you will find corrossion in those unsealed connectors. Had this same behavior on my truck and that was the issue. Unfortunately, I had so much corrosion that my rear AC is now non-functional. Going to be a very expensive repair I really wish I'd found earlier.

These are the stock fog lights. No mods. It did rain last night.

Look at this connector in the d.s. kick panel below the a-pillar:

Water. You have water in your driver side lower kick panel, as shown above. Open it up and dry it out. Thats my bet, same exact thing happened to my 2013 after a heavy rain storm. Sunroof drain was clogged.

To keep the battery from draining, I just pulled the fog light fuse until I got home and was able to open it up down there.

It does look like I have a plugged up sunroof drain.

How do I get access to the drivers side kick panel and fuse box? I don’t see how to open this up

I figured out how to get that panel off - two Philips head screws and a couple tabs. But looking at the manual page 565, this shows the right fuse is number 8. But pulling that fuse doesn’t change anything. Any chance the manual is wrong about the fuse location for the fog lights?

It’s not controlled by the fuse box on the drivers side. I pulled each fuse one at a time.

I disconnected the battery for now. I will reconnect it in the AM and take it to the dealer.

The carpet on the drivers side is wet, so I do think the root cause is the sunroof drain.

I would highly advise against that. The dealer will charge you 100s and probably tell you you need to replace your flux capacitor which will cost 1000s. You can fix this problem in about 30 minutes yourself, its very easy.


Disconnect battery.

Then pull the lower door entry trim, then pull the kick panel to the left. There will be several big, white plugs that are bolted in place, as pictured above. Loosen the bolts so you can unplug them. Take a hair drier and blow it out.


Vacuum out the area around the sunroof drains from above. Feed some weed eater line through the sunroof drains. Pour some water down to test and make sure it comes out under the car.

Put it back together and reconnect the battery.

While you are at it, put a little dielectric grease around the connector to keep any further water intrusion at bay, should they clog again.

You may want to pull the relay that TeCKis300 pointed out above, And then see if they turn off.

Sometimes those relays get stuck in the closed position giving the item power 24/7. I could just be the replay is stuck, and if that is the case just replace the relay.
When you pull it out You can check it with a multi-meter for continuity.

Just solved the exact same issue. After pulling and inspecting all the a pillars and kick panels and cleaning the sunroof drain and finding nothing and blaming it on my windshield replacement, I reread this post and pulled the relay. It's bad. Thanks!
