Motor & Bracket, Front

Start by positioning the front seat to its highest vertical level followed by seat removal before beginning the motor replacement process. Before extracting the vertical and horizontal drive cables from their respective actuators, users must apply force to the oblong connectors for cables (1,3) and disconnect motor electrical connectors (2,4,5). Start by removing the motor support bracket nut from the seat adjuster then use a tool to remove the retaining clip from the horizontal motor and finally remove the motor support bracket from the seat adjuster. Drill out the support bracket's rivets followed by motor removal (2,4,5) from this bracket. Starting with the grommet installation to the motor support bracket you can install the motor (2,4,5) with proper rivets into the grommet and bracket. Before completing the installation secure the motor support bracket nut on the seat adjuster until it reaches 8 N.m torque (70 lb in torque). Drop the retaining clip onto the horizontal motor before attaching drive cables (1,3) to vertical and horizontal actuators by connecting their connectors until you hear a loud audible snap. Purchase the electrical connectors before installing them to motors (1,2,3). Next install the front seat and return it to its original position.

Begin the horizontal actuator replacement process after positioning the front seat to its highest vertical slot which reveals the bolts on the horizontal actuator. Take out the front seat before continuing the replacement of the vehicle's horizontal actuator. The motor support bracket becomes removable before proceeding when the actuator is situated next to the horizontal motor. The oblong connector on the horizontal actuator requires equalization before you can remove the bolts which secure the horizontal actuator. You should remove the actuator from its position in the upper channel. Put the actuator once again into the upper area and then bolt the bolts to the horizontal actuator by tightening them to 11 N.m (97 lb in). The horizontal drive cable must be inserted into the actuator which requires applying pressure until a clear audible click is detected. Reinstallation of the motor support bracket must be followed by placing the front seat back into the vehicle.

The replacement process for front seat adjuster motors requires a front seat adjuster removal while disconnecting electrical wiring harness connectors from both seat adjuster motors. Begin by taking away the seat adjuster motor bracket nut while separating the drive cables from the seat adjuster motors. Spare the motor for the front seat adjuster by removing it from its place. To install the seat adjuster motor connect it to the front seat adjuster while ensuring proper installation of the nut to the seat adjuster motor bracket before tightening it to 10 N.m (89 lb in). After connecting the drive cables to the seat adjuster motors proper reinstallation of electrical wiring harness connectors completes the procedure by installing the front seat adjuster. Service personnel should note that the new Mark II seat adjuster built from VIN 2G1WX15K919298568 onward has no replaceable sections because it requires full assembly service.

Use the power seat switch to position the seat adjuster fully forward and install the rear actuator bolts, tightening them to 4 N.m (35 lb in), then position the seat adjuster fully rearward and install the front actuator bolts, also tightening them to 4 N.m (35 lb in).

Reinstall the front seat.

Install the retaining clip to the horizontal motor, connect the drive cables (1,3) to the vertical and horizontal actuators, and ensure the drive cable connectors are pushed into the actuators until a loud audible click is heard.

Install the motor support bracket to the seat adjuster, ensuring to install the motor support bracket nut to the seat adjuster and tighten it to 8 N.m (70 lb in).
