On the 2004 36ft model their inside the rear left compartment that holds the shore power cord. The fuses are located on the right side behind a metal panel that is held on with a couple of screws. Easy to find if you know their there.
Would that be the rear most wall panel thats held in by 6-8 screws? There is no (small) panel to remove in mine.. 04 36G.. I can see wiring and modules mounted behind that panel..
On my '04 Journey, the factory drove the screws for the storage bay door strut through the panel ... so I had to remove the screws on the back wall ... and the two screws holding the strut before I could get mine out ...
I cut a notch in the panel where the two screws for the strut are so I don't have to do that again ...
