Junction Box

Can anyone tell me where I can find the junction box on my 1999 TJ? I know where the fuse box is behind the glove box and the power distribution box under the hood. I'm trying to diagnose why my cigar lighter receptical isn't working. I read online there are 2 fuses in the junction box that could be the issue, but for the life of my I can't find it and nothing online can help?

There's no "junction box" in a TJ, the only two locations that contain fuses are behind the glove box and inside the power distribution center.

And a big welcome to JF.

When you have a choice, buy American made.

On your ’99 there is a relay for the lighter. It is under the dash in the left side near the steering column. Power to close the relay comes from the ignition switch when in the on & acc positions. Then power comes from fuse 5 in the PDC to it & when closed (key on/acc) it sends power to fuse 19 in the fuse block behind the glove box which sends power to the socket. Find the relay & see if it is clicking closed when you turn the key on. If good, check both fuses with a meter since they can often look good but be blown in a spot hard to see.

Power to your lighter/accessory socket goes from the battery, through fuse 5 (40A) in the PDC, then through the lighter/accessory relay to fuse 19 (20A) behind the glove box and on to the socket. The relay is located on the side of the bank of connectors that are behind the driver side speaker. Easiest way to get to that is probably by removing the panel below the steering wheel.

One thing that can stop the sockets working is the center contact getting dirty and stopping conducting. If it looks dirty and you want to try scraping it clean, make sure the ignition is off so you won't short a fuse.

Thanks that why I couldn't find it. Would you know what fuses are for the cigar lighter? The owner's manual only maps out the 1 behind the glove box doesn't call out a fuse for the CL.

Fuse #5 (40A) inside the power distribution center and fuse #19 (20A) which is the most likely culprit behind the glove box.

The one labeled Cigar LTR.
