Where are the fuses?

Yes

 

UPDATE:

The fuses for the 12-vDC receptacles in this 2015 Pete are listed as 'cigar' on the schematic and are found in all kinds of circuit breaker boxes all over the truck near the receptacle itself.

The techs at our Winter Haven shop replaced all the bad ones and I found one what I think is a bad receptacle; as soon as I plugged my test pigtail in, it failed again. Replacing the unit is a lot more challenging than merely replacing a breaker.

The biggest aggravation is it's one of the two up front that I wanted to just from my GPS or satellite radio. They will just have to keep sharing one, I guess.
