GEN1 No power to upfitter/AUX switch

[apollo90]

Hi everyone.

Two of my upfitter switches suddenly stopped working: AUX 1 and AUX 4. There doesn’t appear to be power to them as the indicator lights do not illuminate. I checked fuse 18 and 28, which I have read correspond to these switches, and the fuses are good.

No new wiring recently.

Also my sunroof and rear window open, as I heard some say that fixing the BMC relay sometimes has helped.

Please help! Thank you

most likely a bad aux panel if fuses and relays are good. and wires not shorted.

Fuses and relays are all ok. I didn’t think the panel itself would be bad. I’ll give it a shot. Thank you

Bumping this one up - did replacing the aux panel fix your issue @apollo90 ?

Would also like to know, I am experiencing similar issues, except my lights are still on on my switches

Same, all my switches have indicator lights but only Aux 2 provides 12v. The relays all click when toggling the switches so I think they are working. They also seem to be mislabeled according to the manual but maybe that means a previous owner removed it and miswired it?
