I would either pull the seat out and make sure nothing is binding up underneath, you may be able to grease the lever and everything involved with the track.

Either that or replace the seat track.

No, the track has a lock on each side that will hold the seat in place. i've seen a few of them get a little rusty, and they don't fall down into the locking position. Greasing these will allow the locks to slide into place. Once you remove the seat and turn it upside down, you'll see what I'm talking about if you play with the seat lever. This is a manual seat, and not power correct?
