Any advice before I take the truck to someone?

[SCAR911]

My auxiliary 5 switch goes to a air compressor that's where the spare used to be. Has worked forever. Went to use it to air up tires and noticed the switch in the truck was flipped. Odd. Now it doesn't work. Is there any specific fuse somewhere that would run aux 5? Tried to look in the manual and check fuses but it seems vague on what's really what for those switches. Anywhere to troubleshoot?

Check the fuse under the hood:

Fuses for those switches are in the engine compartment, towards the back on the passenger side

This happened to me and it was just the wire in the cab had come apart. Does the light come on the switch?

Yup. Light it on.

Up fitter 5 relay?

Could also be the connection under the hood, or wherever you tied into the upfitter lead.

It was all done when I bought the truck. Is all 6 switch connections in that panel next to the fuse box under the hood?

Mine were actually behind the big bundle of wires going into the firewall there… Where those two big connecters plug in on the passenger-side firewall:
