2011 Ford Ranger Sport - Fog Lights staying on

[Gunner862]

Hey all,

I was at my Bother's place tonight and noticed my fog lights were on despite everything else being turned off. I could not get them to turn off without removing my 15A fuse. I swapped relays but no change. The control side of the relay seems to be shorting to Battery (+) (I think). Normally the fog lights only work when the key is turned on and the headlight switch is pulled out. Switching to high beam turns them off which is normal. I played around with the fog light switch, ignition switch and multi-function switch in different combinations, sometimes the fog lights momentarily turn off (with all other switches off) but then come on again shortly after.

I'm wondering if anybody has come across a similar problem, and if so, what was the solution. I have yet to check anything and just have the fog light fuse removed for now so the battery doesn't drain.

Your foglamp relay is controlled by grounding the brown wire between the underhood fuse box and the underdash fuse box. These are "smart junction boxes". They are fuse boxes with electronic circuit boards underneath.

If you pull the relay under the hood, the foglights go out?

Yes, removing the underhood relay also will make the fog lights go out. I can hear the relay click on as soon as it is plugged in (with the 15A fuse also in).
