  Q: How to replace the front seat motor for the power recliner on Buick LeSabre?

  A:

  One must disable the SIR system before starting to replace the front seat power recliner motor. Begin by taking off the front seat before separating the inner seat adjuster track cover together with the inner recliner trim cover. The power recliner motor will become accessible by partially taking off both the seat back cover and pad. The power recliner motor requires detachment of electrical connections together with recliner position sensor connections when present. The replacement of the front seat power recliner motor begins with removing a push-on nut from the end of the recliner rod as well as the fastener that secures the recliner motor to the seat back frame. The recliner rod must slide first from the seat back recliner before it can slide out of the power recliner motor. Remove the power recliner motor from its seat position. To continue proceed remove the female recliner position sensor from the recliner motor. First place the recliner position sensor on the recliner motor while ensuring to have the recliner position sensor equipped and then put the power recliner motor into the seat back frame. Introduce a new push-on nut onto the end of the recliner rod after sliding it through the power seat back recliner motor and recliner assembly. The power recliner motor fastener should be installed and tightened with 9 N.m (80 lb in) torque. Replace the wiring harness back to its original spot and attach electrical connectors to both the power recliner motor and recliner position sensor if present before putting on inner recliner trim cover and seat adjuster track cover, seat back cover and pad. As a last step you must install the front seat while enabling the SIR system.

  Q: How to Service and Repair the Seat Motor on Buick LeSabre?

  A:

  The first step for seat adjuster motor replacement requires SIR system disablement. First remove the vehicle seat and its cushion to reach the seat adjuster motors. Determine which adjustment motor requires replacement among the vertical rear motor, vertical front motor and horizontal motor types. Disconnect both seat adjuster drive cables as well as the electrical connector which connects to the motor assembly. The bracket attaching motor inserts from the factory need removal. Drill out the factory motor insert from the seat motor plate bottom side by using a 3/16 in drill bit while the seat rests on a dry clean surface with its back facing upward. Position the new seat adjuster motor (1,2,3) on the motor plate and fasten it through the motor insert placed into the motor grommet of the new motor. Use the bolt to fasten the motor onto the motor plate while tightening it to 4N.m (36 lb in). Install the motor and cables while also replacing the electrical connector then put back seat cushion and seat into the vehicle. To complete the operation enable the SIR system while performing memory seat calibration as needed.
