I just bought a gx460 and my driver seat has the 8 way adjustment but when I try to adjust the front part of the seat up and down, I hear a noise but it does not move. It seems stuck in the up position. all other functions seem to work properly.

 

I must have missed your post a while back. Still a problem?

 

I had this same problem on my old LX - I took the switch control out of the seat, opened it up, and there were several pieces of broken plastic that were jamming up the control. If you physically can't move the switch, that may be the problem.
