84 Power Seat Relay

I've searched around, but can't find a definate answer. My 84 has a power driver's seat, which does not work. I have changed the fuse/relay in the fuse box, and still nothing. There are two boxes/relays mounted under the passenger's seat. I've read that those are for lock/unlock on the power doors (which don't work either), I also read that one's for the buzzer, and that one's for the door locks and that one's for the power seat. Anyone know for sure? Luckily the seat's stuck back (I'm 6'4"), but my wife likes to drive it sometime, but it's hard for her to reach the pedals. Any clues? Thanks!

There is no power seat relay. Power runs directly from the fuse box to the seat switch to the seat motors. I think the thing you are calling a relay in the fuse box is the self resetting thermal circuit breaker.

Their are no relays. I would pull the switch and test it with a DVOM.

None of the seat switches work, the joystick and the front and rear tilt switches? If none work I would first check to see if power is getting to the switches. The two relays under the passenger seat are for the door locks. The door lock motors are the most likely suspect. If the window seals are worn and allowing more than a little water into the door they can go bad easily. I've replaced my door lock motors at least three times. Since replacing the window seals and wipes they've held up.
