REMOVAL & INSTALLATION
See Figures 1 and 2
The six-way power seat adjusters are actuated by three 12V, reversible permanent magnet motors with built in circuit breakers. The motors drive the front and rear vertical gearnuts and a horizontal actuator. When the adjusters are at their limit of travel, an overload relay provides stall torque, so the motors are not overloaded. Each motor can be serviced as a separate unit.
- Disconnect the negative battery cable.
- Remove the seat assembly from the vehicle as outlined in this section.
- Remove the adjuster assembly from the seat.
- Detach the feed wires from the motor.
- Unfasten the nuts securing the front of the motor support bracket-to-inboard adjuster. Partially withdraw the assembly from the adjuster and gearnut drives.
- Remove the drive cables from the motor. Completely disassemble the support bracket with the motors attached.
- Grind off the peened-over ends of the grommet assembly securing the motor-to-support. Separate the motor from the support.
See Figure 1
- Drill out the top end of the grommet assembly using a 3 / 16 inch (5mm) drill bit.
- Install the grommet assembly-to-motor support bracket. Secure the motor with a 3 / 16 inch (5mm) rivet.
- Install the drive cables.
- Install the motor-to-inboard adjuster.
- Connect the motor feed wires and negative battery cable.
- Install the adjuster assembly-to-seat bottom.
- With an assistant, install the seat and check for proper operation.
See Figure 2
- Operate the seat to its full up position and about 3 / 4 full forward.
- Loosen the 2 actuator screws.
- Pry out and, at the same time, energize the horizontal switch to move the seat fore and aft slightly.
- After the gear teeth free-play has been eliminated, maintain the outward pressure and tighten the 2 actuator screws.
