Slide Lights Not Working Shadow Cruiser 280QBS

[Farbeyondone]

I own a 2018 Shadow Cruiser 280QBS.

The interior lights in the slide don't work now. The fuse is blown. The outlet works fine.

I've replaced the fuse only to have it blow right away. (Yes I disconnect the battery and the power before replacing)

Any ideas on what it may be?

I looked at all the wiring under the dining area and the sofa...it all appears to be in tact and undisturbed. I took all the lights off and checked for damage/corrosion but I see nothing concerning.

I don't know how to test the actual wires when the fuse pops each time I put a new one in.
