My driver seat in a 2004 3.0 wont move forward or back. Has anyone experienced this. It does everything else just fine. With the exception of the front of the bottom acts as if it is stripped when you try to raise it. Today when my wife tried to move it forward the motor clicks once as if it would move, the seat move appx 1/4" and thats it. It does this forward and back. Does it sound like the motor? If so can it be replcaced or would I need an entire seat? Thanks in advance.
