The first thing to do when servicing the power seat motor is to make sure the battery is safe by disconnecting its negative cable. To work on the front tilt motor, first remove the seat with the motor that does not tilt, then remove the seat's cushion and pan. Seat motor disconnection starts with taking out the fasteners holding it to the seat adjuster and then removing the electrical connector from the motor. For installation, set up the motor on the seat adjuster, screw it in until the force is 5 N.m (44 in. lbs.), connect the cable, replace the
Seat Cushion, fasten the wire harness to the pan underneath, reassemble the seat and connect the battery negative cable, checking the system works properly. If the height adjust motor is not working and the seat is neither fully lowered nor fully raised, take care, since the assembly may be loaded. Separate the battery negative terminal, get rid of the problematic motor seat and remove the seat's pad and pan. First, disconnect the connector for the motor, take off the screw and washer from the motor shaft and then remove the fasteners tightly holding the motor to the seat adjuster. When putting in the motor, first raise the seat adjuster fully, place the motor where it will fit, add the motor shaft screw and washer loosely, cover it with screws tightened to 9 N.m (80 in. lbs.) and then tighten the motor shaft screw and washer to 6.5 N.m (57.5 in. lbs.). Restore the connection of the motor wire, place the seat cushion back in position, join the wire harness to the pan, assemble the seat, link the negative battery wire again and see if the power seat is working properly. Replace the height adjuster assembly immediately if you find a loose locking pawl, locking pawl active in the seat frame or a broken or missing shear pin.
