Given that it is 2020 model, more than likely there are no junction boxes under slides and you will find the 12vdc line as a black rubber covered stranded cable at the rear end of the slide. So what they do is transistion from normal 12vdc wiring near the back of the slide, out through a hole in the slide floor, across the gap in the folding line keeper you see under there, into the back corner of the rv where it again transistion from the rubber covered cable back into normal 12vdc wiring. You may be able to find the inside transistion hookup to check it, but the rear of the rv transistion will mean dropping the cloroplast bottom to find the other end. Good luck with your hunt for the bad connection.
