Locate the access panel. This is where you will access the slide out motor and the manual override switch. The location of the panel varies depending on the Jayco fifth wheel model. In most cases, it is located on the underside of the trailer.
Remove the access panel using the screwdriver. There are usually several screws that will need to be removed along with accompanying washers. Take care not to lose any of the pieces.
Turn the manual override shaft using the drill and the 5/16-inch hex head. This will move the slide out in and out, just as if the motor was doing its job properly.
Replace the access panel using the screwdriver. If you removed the panel to open the slide out, it is okay to leave it off so that you can more easily close the slide out at the end of your trip. Do not drive the vehicle with the access panel off, however.
