12V Accessory Oulet Short

I have a 2014 JK Oscar Mike with an apparent short in the 12V Accessory outlet on the front dash. I recently had an Eaton E-Locker installed in the rear differential, and the installer tried to tie it into the 12V Accessory wiring (at the fuse box I presume). He told me that it kept blowing fuses and that he tied it into an alternative 12V source. I got a dash cam for Christmas and went out to the car to plug it into 12V Accessory plug, and got no power. I presume that the fuse is blown again.

My question: Has anyone else had a problem similar to this, and if so what was the resolution? Any suggestions for troubleshooting this electrical fault. The 12V Accessory outlet in the back by the sub-woofer still works.

You're going to have to check the fuse, replace if blown. If it keeps popping fuses, then start looking for the short. It could be a pinched wire, or bare spot.

He may have tried to tie into it under the dash. If you remove the glove box you'll find the wiring going down the left side of the opening. He may have pulled the wire too tight over the metal brackets or left a bad splice. Just so you know, your back outlet and the one in the console are both on different fuses than the one for the front dash. (They are on fuses M7 & M36 respectively.) Also, check inside the socket. I know, sounds weird, but I once had a plug that disassembled itself and left its tip inside where I couldn't see it. The tip would bounce around and blow the fuse...

Thanks for the reply bobchase,

I took the glove box out, but you can not access the wire because of a ducting obstruction. I verified it is shorted with a volt ohm meter continuity check (back of the plug-12V to side of the plug-ground). I visually inspected the plug internal and it has not shorted itself. At this point I don't feel comfortable tearing the dash apart to get to the wiring, so likely a trip to the Stealership.
