If it's a limited or SRT6 you might have a bad seat relay.
Search the forum for how to replace it. The search bar is in the upper right where it says "Threads". The part is cheap and should be available at most part stores.
If it's a base or SE you might have something stuck in the seat rails that is preventing you from moving the seat.
