Ask and ye shall receive...
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).
