Question '85 Bonneville Power Seat Motor

I was given an '85 Bonneville Brougham that I need to do a few things to before I can drive it. One of those things is to fix the front seat adjustment - the motor just spins and won't move the seat. The seat is currently forward all the way (I believe) and up higher than I would like - I'm 6'2", 240lbs so I really don't want to feel as though I'm trying to wedge myself into a 1970'* compact Unless I'm missing it, I can't see any way to unbolt the seat from the floor in its current position which leaves me with the option of trying to remove the motor from under the seat as it is. "Theoretically" it should be possible but I'm not entirely certain how the motor assembly is attached to the seat railings as I couldn't get a real good look at it when I popped my head under there earlier... Anybody here have any experience with this? Is there any way to manually move this seat back and down? If I can just get it where I like it, it won't really matter if the motor works or not - I suspect it may have a stripped gear anyway... If anyone has any ideas, it would be greatly appreciated. Thanks

I have an '84 and had the front seat removed to be reupholstered. A call to an upholstery shop may help shed light on removing the seat. If you decide to replace the seat motor this website may be of some help. Car-Part.com--Used Auto Parts Market

Hope this helps.

(Hey, if we keep posting one reply here every two months, we oughtta have this worked out by 2015 or so, no problem...

If the motor is actually spinning freely, I don't think the motor is the problem; it may be a drive cable that'* come off. I had to get a genuinely dead motor out of an old Bonneville once, a '78 I think, and I remember its setup was just one flexy steel drive cable going from the motor into a solenoid-activated gearbox that moved the seat frame in various ways, depending on which solenoid would engage. If you can see anything at all under the seat, see if you can eyeball the motor and the cable to the gearbox. Maybe something'* come apart.

Worst-case scenario: I'd see if you can remove either both front or both rear seat track mounting bolts, whichever set is currently accessible, at which point you may be able to flop the entire seat assembly forwards or backwards just enough to get room to work underneath. Be sure to brace the seat up really well with wood or a toolbox or something. There are plenty of sharp edges underneath.
