Rubicon Aux Switch #4 not working - Need some help/advice?

[MarkyMark]

Need some help here. . . I have the Four Accessory Switch option which comes as an option from the factory on the Rubicon. Switches 1, 2, and 3 are working fine. Switch #4 is dead - both on the wiring inside the cabin and in the engine bay.

A little back story: It was working. I had my on-board air hooked too it. It stopped working, I believe due to a faulty connection. While troubleshooting it I sparked briefly between the wire and the ground. It stopped working completely. No big deal I figured as I likely just blew a fuse. However. . . There don't seem to be any fuses for these things from what I've been able to find. Hoping one of you guys who is smarter than me knows where a fuse is or some other sort of trouble shooting.

The switch light still lights up on #4, it can still be programmed in the Uconnect, everything acts like it works. . . just no power to it when on. Like I mentioned, switches 1-3 are working fine. Thanks in advance!

You blew the fuse to it. Aux 4 is only a 15 amp wire, too small for an air compressor.

Look at your owners manual. F108 is for Aux 4.

As already mentioned, you undoubtedly blew fuse for Aux 4..


With -Factory installed - Aux switches, here is the fuse list in regard to Aux .... Aux 1, 2, 3, 4, and also the Direct to Battery and Ignition Switched, wires which are only found in the passenger foot well, Aux bundle.

These fuses are found in the power distribution center (PDC) next to the Main battery.

F50 HD ACC — If Equipped 10 Amp Red Micro < Ignition switched wire in pass foot well

F72 HD ELEC ACC PKG — If Equipped 10 Amp Red Micro < Direct to battery in pass foot well

F92 HD ACCY #2 — If Equipped 40 Amp Green Cartridge < Aux 2

F93 HD ACCY #1 — If Equipped 40 Amp Green Cartridge < Aux 1

F103 HD ACCY #3 — If Equipped 15 Amp Blue Micro <Aux 3

F108 HD ACCY #4 — If Equipped 15 Amp Blue Micro <Aux 4

@Rhinebeck01 Thanks man! You're a #rockstar! I looked all over and didn't come up with that. I am not strong on the electrical front. . . but I do have the on-board air running through a relay so should be fine with that. Undoubtedly blew the fuse when I arc'd the two wires together. I'll mess with it a bit later today. Appreciate you man! Happy Sunday!
