What fuse works my sofa bed on my 1994 Ford econoline van any help would b grate

Hello, Most conversion vans are assembled by third parties, so there is not a great way to know without digging into the van, hands-on. My advice is to check for power at the switch, check that the motor is grounded properly, and check that pressing the switch sends power to the motor. Also, most of these have a little service compartment built into the footings on the bed, so check for a little door/access panel. There you should find your fuse panel.
