94 850 - Dead pasenger seat

[JKBrown]

I'm not sure exactly what happened to cause this, because I was away, but apparently my son and one of his friends were giving each other rides on the passenger seat of my 850 by sitting on the headrest of the reclined seat and operating the controls. Well, something got tripped, broken, or hit some sort of limit switch, because now the seat is fully reclined but:

1. I get no motor noises in any axis - recline, tilt, up/down, or forward/back
2. The driver's side still works fine (I think these are both on the same fuse).
3. The wiring seems OK - the cables are still connected

Any ideas?
