the driver side power seat can only recline and will not return back up nor will it move forward/backward what could cause this.

Sounds like your seat mechanism is failing, this is actually a pretty involved system, believe it or not a new seat in a car like yours is about $2500. So it is best to have a shop look at this and see if they can resolve what motor or cable or lever is defective, so you won' t have to buy a new seat.
