The motor that controls the forward seat movement is either bad, or the circuitry is faulty to that motor.
If you intend to do your own work, the motor assembly can be replaced, but you may have to drill rivets from the motor housing that connect it to the seat frame, replacing them with screws to hold on the new motor.
The first thing to check is to ensure that you have power going into the switches, and power coming out of the switches when they are depressed, which can be done with a test light grounded to the chassis. On one wire, the light should be lit constantly, on the other side, the light should only be on when the button is depressed.
Check that the wire connected under the seat is not corroded or broken. Upon removal of the motor, you can test it with any 12V source at the connections. If it spins, your problem is elsewhere in the circuit.
Replacement has no special procedure, but care should be taken to ensure the proper installation of wiring to prevent the chance of fire or damage to other electrical components.
The seat should not move when the motor is not engaged, so the answer is no, there is no manual adjustment of the seat.
You may be able to move the seat rails by hand if you remove the seat and loosen the motor assembly from the track, then replace the motor assembly after you've adjusted the seat approximately where you would like it. The motor assembly is on the bottom of the seat, attached to the pan and adjustment rail.
You can try removing both switches and just putting a jumper wire across from the power to the "reverse" side of one of them. If the switches are held in opposite directions, the motor will not operate, since it will develop field in both directions, effectively canceling each other out.
One of the switches could be shorted in the forward direction, so disconnecting one switch at a time and testing the other one for operation may get you a result. If neither, try putting a jumper from a known power source to the wires in the switch and check the seat for movement.
This will happen sometimes when a seat is put as far forward or back as it will go. To fix usually all you have to do is not sit on the seat operate you're switch in the diection you need to go and use you're other hand to help get the seat started moving. What happens is it is past or against the stop settings and needs a little help getting started again.
You can check on the motor near where the wires go in some of the manufacterers install a button that you can press to free wheel the motor to allow you to readjust the seat till it is repaired.
Try pulling the fuse out for a couple of seconds. It has just gone a little farther than it should. Or, have someone push on the back of the seat while you push the button.
