If the power seats in your car aren't working, you may be able to move them with a winder tool. The winder looks like a cable with a handle on one end and a screwdriver-like bit on the other. Insert the bit into the matching socket on the bottom of the seat and spin the handle to move the seat backward and forward. The seat's movement will be slow and limited to back-and-forth movement, so you may still want to get the power seats repaired.
