Removal- Seat Height Adjustment Motor
Disable the airbag system before attempting any component diagnosis or service of the front seats, when equipped with front seat air bags. Disconnect and isolate the negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.
Use caution when removing the height adjust motor and gearbox assembly (2) if the motor is inoperative, and the power seat is not in the full up position. The seat adjuster assembly is under load from the height adjust assist spring and may cause the motor to rotate under pressure when the fasteners are removed. The seat adjuster assembly also may spring upward when the motor is removed. If the height adjust motor is operative, move the power seat to the full up position prior to disconnecting the battery.
- Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.
- Remove the inoperative front seat. Refer to SEAT, FRONT, REMOVAL .
- Disconnect the height adjust motor electrical connector.
- Remove the height adjust motor gearbox spindle (1) retaining screw (4).
- Remove the motor retaining screws (3).
- Remove the height adjust motor and gearbox assembly (2) from the seat track.
