Question Upfitter Switch Stopped Working

I realized this morning that the upfitter switch on my '10 E350 6.0L Diesel doesn't seem to be working. It controls the fog lights and on-board air and neither power on. I checked the fuse that the manual states controls the switch and that didn't fix it.

Any other simple things to try before I take it my electronics guy?

Thanks in advance.

There is also a relay corresponding to each switch.

If your 2010 is like my 2012, then:

Sw 1 = relay 85 & fuse 19 - 30A
Sw 2 = relay 62 & fuse 20 - 30A
Sw 3 = relay 8 & fuse 44 - 10A
Sw 4 = relay 7 & fuse 45 - 15A

Schematic can be found in the body builders layout book.

Garage
We have a 2014. Had a loose connection in the upfitter wiring bundle forward of the firewall (located in the top right of the engine compartment). This was causing the switch to fail. It was an easy fix. As noted above, the wiring diagram can be found online. The wire colors were distinct and made it easy to isolate each switch.

Turns out the folks who installed a new stereo just forgot to plug the switch back in! Fortunately that's a free and easy fix.
