2017 Coleman Lite 3025 slide out

BIL has the subject trailer and the main slide out has stopped working when he came to visit. I was able to run electric directly to the dc motor and got it to open, so I know the motor is good. All the fuses in the box look ok and bypassing g. The switch doesn’t seem to help. Is there an in line fuse somewhere that we are missing. Searched a bit, but not finding anything on the net.
