02 Q45 drivers side power seat is jammed. No for and aft movement. Motor works left track tries to move, but right track is jammed. Seat is stuck aft so rear rail bolts are not accessable. I assume only 4 bolts hold the rails in. How do I get the seat out? Dealer says repair parts are not available only a complete rails and motor kit is available for $616.00. However I must first get the seat out. Please help me.
