When I see the price of OEM I think aftermarket.

Initial issues
#12 blows on insertion.
#13 blows when ignition goes to ON.
Braklights out, bulbs burnt.
Dash cluster out.
Aftermarket stereo would not turn off.

Flashers and turns work.

Quick look under the dash behind fuse panel found 2 conjoined light ga wires. White / tan and GREY/RED. Repaired that.

White tan brake lights , I think. I only have a crappy clymer wiring diagram. The other ?
Now I pulled the fuse panel. Not sure how to proceed, having found nothing obvious.

Removed aftermarket stereo. THANKS !

PS.....
The wh/tan and grey/red small ga wires were melted together for about 8 inches. This is just at the connection block behind the interior fuse panel, lower left of the large connectors on the back of the fuse panel. Of course, someone has been in there previously. This rig was outfitted with elaborate towing set up front and rear.


Back to the melted wires... can a guy follow the circuits through the panel from fuse sides to the wires where they come out of the connector ? Would this show whether the panel is ok, including the BCM ? I'm tempted to put it back together if it wasn't such a pita to do again. Would of course be a step forward if this part of the process could be eliminated.

Sounds like dead short some place. Is there history of water submersion? I'd start with removing and disconnecting anything aftermarket.
Double check for an aftermarket trailer wiring adapter/converter.

What is fuse #12 and #13 for?

Quick look under the dash behind fuse panel found 2 conjoined light ga wires. White / tan and GREY/RED. Repaired that. I assume melded together?????? If so, this is a sign of something got hot and the fuse did not do it's job. Maybe the fuse was by-passed. From what you posted it sounds lights related. I'd comb every inch of wiring harness for modifications, heat damage or places where it might short out. There are places on the net you can download the OEM service manual in pdf. BTW pull each connector apart and look for damage or corrosion. Do you know the history of the Jeep?
Cheers,

Ok... From the owner's manual... fuse 12 is stop lights.
Fuse 13 is body control module, CMTC, Pass airbag on off indicator,auto daylight mirror, and light bar switch (renegade).

The fuse panel in question is inside the jeep. Left side, under dash on the left.

Thanx vtec for the pdfs.

#12 is clearly shorted.
#13 blows when key goes to ON.

No submersions.

This jeep has towing set up front and rear.
