I'd check the fuses first. There was a recall on either (or both) the 94 and 95's for the seat harness. It came tie strapped to the seat frame, and could over time wear through the insulation and cause a short or fire. The fix was to unhook it from the seat frame. I'd check you wires for damage. Perhaps this happened and blew the fuse.
Perhaps your motors are burnt out.
FWIW - My power seat track only goes front and back - up and down doesn't work. I've never took the time to figure out what the problem is because I don't ever want the seat higher up than it's current all the way down setting. Kinda nice not going up and down, so no one else will monkey with my settings (up and down anyway).
everytime i put a new fuse in it would blow, i gave up and my power seat doesnt work anymore, but i dont care anyways because now no one can mess with where my seat is.
You probably have a wire shorting out somewhere. I'm with you on the 'saving your spot', but I just discovered that if you need to take out the seat, the bolts/nuts are covered and much more difficult to get out (but not impossible).
