1990 Ford Econoline 150 van: My Sofa switch is not doing anything so I'm assuming a fuse has blown but no fuses are blown in the fuse box by gas pedal. Anywhere else I can find the fuse for this?

Inline fuse in cable to motor? Break in the line? Failed motor? Mechanical jam?
29 years old electricals in a van are always questionable.

It's a high amperage motor, so it probably has a relay switch in the engine bay power management box.

In a custom installation like yours, a fuse could be almost anywhere. You'll have to trace the wiring to find it.
