Aux System problem

[vavaroutsos]

today i tried to follow the wiring to find a fuse or relay but i couldnt,i even check inside the car on the passenger side for fuse or relay but nothing ,, i looked were the brake boaster and nothing, change the ground and still nothing ,, this is getting me crazy . i dont think the dealer will put the fuses in a hiden place cuz it will be dumb of them .. i just have no clue what to do.

Can you post some pictures of your PDC with the cover off showing the aux fuse/relay locations and one of the brake booster area along the firewall?

Hi guys, i have an 2018 JLR that came with the AUX system from the factory, it was working fine until one day i discovered my spot lights are not working but the aux buttons lights normally. i dont know what the issue . i tried looking for fuses or relays but could not figure out the location of them,, anyone could help me in this issue.

Go FROM EASY TO HARD:
If the fuse(s) are good, I'd check the ground first, to rule it out.
Then turn on the switch and use a tester to check the power going into the light.
If they are both good then its the light itself.

Relays and fuses are in the PDC (power distribution center) for factory installed switches.

BTW, where are The spots located, could u post a pic?

See post #5 in this thread. I don't have dealer installed switches on my Jeep, so I can't take a picture of that type.

here you go, that is my fuse box

Ok, I don't see the black relay box for dealer installed aux switches (by the brake booster), so I assume you have factory aux switches. That being said, you should have relays in K17, K18, K20, and K21. It does look like K20 and K21 have contacts loaded (I can't tell on K17 and K18). You said things were working, then they weren't, so did someone play a cruel joke on you and pull parts from your PDC?

do you think i should put fuses in these slots ?

The Kxx slots are for the relays. The fuses should be in 92, 93, 103, and 108. No way you are going to get power to an aux load without the relays. The switches are soft switches. They communicate over the CAN bus to the PDC, which energizes the relay coils to switch them on. The relays are what switches the power for the aux circuits.
