Rear Fog Light Fuse?

[Hayesio]

There is a wiring diagram here, page 20:

When you say "rear fog lights" do you mean rear park lights?

Lift up the fuse box lid and you will find the schematic and fuse list on the underside of the lid. I have it here in .xps formate but it wont let me upload it. It appears the park lights are fed individually, M17, M18, and these fed other circuits so if you only have issue with park lights, fuse probably not the issue. Could be a ground connection (but again, unlikely because ground connections on the rear light cluster are common). As suggested, make sure you are operating them correctly.

Its rear fogs he is chasing.

Also worth checking the cable has not got caught on something and pulled out. The cables are under the back left corner and the plug is a foot or so forward on the chassis from memory.

Though to be honest I have never used the rear fogs on any vehicles I have owned. Only time I see them used is by idiots who dont realise they have them on and cannot understand why everyone behind is flashing them (usually Hyundai SUV's up here). So annoying sitting behind someone with them on. Might be ok in extreme fog I guess.

Thanks for the schematic Hayesio. I think there must be some differences in the wiring between the US and Export versions of the Wrangler that aren't in the diagram. I couldn't see a specific mention of the bumper mounted rear fogs at all, also not in the fuse box lid.

I checked for B+ with a multimeter at the plug you mentioned SeaComms, and all checks out from that point so it must be the unlikely co-incidence of two blown fog light bulbs. Will chase that down some other time, but good to know its not a wiring gremlin elsewhere.

Thanks for the tips folks!

Cheers,
