The odds are that the power seat problem is due to the switch not making contact. You could remove it (the buttons pop off, then the switch itself pops out and can be unplugged.

Some tuner cleaner might solve the problem without opening the switch. Do a search here and you will find how to repair the switch and not spend the $80+ mine cost because a couple of tiny ball bearings escaped.

There is a cross reference here to a land-Rover site where you will find very thorough directions and photos about repairing this switch. Dremel (or super cheap Harbor Freight clone) will be useful here.

Your car is probably quite similar to the $3600 average car according to Kelley.

It's really a matter of luck vs sure thing: if you fix your car yourself, you know what is new. If you buy another car you might just luck off and buy one in better shape that has had most of that expensive stuff intact or replaced recently.
