OK, Zachee, you got me thinking about my system , I wasn't sure if my slide motor was fused or had a 12v circuit breaker.
So I went to my coach and checked. A 20 amp fuse protects my slide motor circuit.
So your going to have to search the RV for the fuse panels , they may be hidden behind removable panels, so if you find a panel held in by screws or Velcro , you need to take it off and look behind it.
I'll detail the way my coach set up is wired and put some picture in so you know what to look for .
From the fuse panel the power goes to the slide motor control box, The control box takes the signal from the slide activation switch , then provides the motor with power and ground; to move the slide out, and stops supplying power when the slide has traveled to it's limit.
To move the slide in the control box reverses the power and ground, and the slide motor runs backwards to bring the slide back in.
I am not 100% sure if this is the system your dealing with , but this is a very common set up for slide control.
The slide motor and drive gear reduction , shafts and cogs are under the slide floor and on my coach visible with the compartment doors open.
If you can't find the fuses or your slide drive doesn't look like this , maybe you should repost to the " Owners Forums " to the brand your working on and ask where the fuse panel is, not everyone looks at post in the Appliances forums.
