sounds like your getting power 2 some of the seat motors. i think there are 3. 1 forward-backward 2-raise and lower 3-tilt forward and backward. it might be 1 of these motors that are not in sync or your seat itself could be jammed. go 2 the library and see if they have a repair manuel for lincoln and marquis. or buy a chilton manuel at a auto store. its really handy 2 have and covers most of your car. good luck mike
