Power seat won't move forward

Good afternoon. I'm new here & not familiar with how to post, so please
forgive if I've posted incorrectly. I have a 1996 Towncar with over 225,000
miles on it with driver seat issues.
If you use the remote to open the car & the seat moves back, it will not go
forward. You'll have to sit for 10 minutes or so inching it forward in small
increments before it will reach your comfort area. Or you can stuff something
behind you and drive for 10 minutes or so & then the button will move the
seat forward. The seat will go up & down & backwards, but not forward. If you
punch in the code on the door panel, the seat doesn't move & you're fine, but
if anything moves the seat backwards, ie you turn the car off & get out or you
use the remote to get in, you will be sitting there for a while trying to get the
seat back into position. Can someone please help with a suggestion? Thank
you in advance & apologies if I have posted incorrectly.
