  Q: How to Replace a Rear Seat Cushion Pad and Seat Cushion Pad on Buick Rainier?

  A:

  Vehicle users must start seat back cushion cover and pad replacement by removing the seat back from the vehicle before removing the seat belt buckle bracket on the right side followed by the seat belt anchor bolt from the bracket. Push down on the buttons installed on plastic retainers followed by seat belt bezel release so you can pull the seat belt away. Before proceeding with the seat back operations, first remove the head restraints and then remove the release latch knob and finally the screw holding the seat back latch release bezel. Secure the bottom seat back J-strips and hook and loop retaining strips before removing three push-pins from the bottom area yet keeping the hook and loop strips adhered to the seat back pad. First detach the cover from hook and loop strips on the front of the seat back pad before using pliers to remove the 6 push pins from the seat back. Then take off the cover and pad together. Move the logistic hog-rings off the reinforcement bar as you take away the seat cover from the pad. You should mount the seat back pad onto the seat back frame by using all six push-pins for installation. After partially applying the seat cover you must secure the 3 hog-rings onto the reinforcement bar before finishing the seat installation process between the hook and loop retaining strips found on the seat back pad. First install the screw that retains the rear seat back release latch bezel at 3 N.m (26 lb in) before tightening all the 3 push-pins located at the bottom of the rear seat back. Reconnect the hook and loop retaining strips as well as the J-strips at the bottom before reinstalling the head restraints. To install the seat belt bezel on the rear seat back, use plastic retainers first while you should install the rear seat belt anchor bolt to the seat belt buckle bracket by tightening it to 55 N.m (41 lb ft) before you replace the seat belt buckle bracket on the right side.

  Q: How to replace the front seat cushion pad and cover on Buick Rainier?

  A:

  You should start cushion pad and cover replacement by unscrewing the seat switch bezel screws with three bolts together with the four nuts which connect the seat pan to the seat adjuster assembly. The front outboard seat pan stud should have its clip removed by those with equipment before disposal. Start by releasing the J strips from both sides of the seat cushion and then proceed by removing the front as well as rear J strips. The first step involves removing all attachments between the SIR electrical harness and seat electrical harness from the seat pan along with removing their fasteners. To proceed remove the seat cushion heater electrical connector from its connection point if installed. The adhesive-backed strip of the seat pad should remain untouched while using the hook and loop retaining strips to separate them. Remove one hog ring from the bottom rear side of the cover while unfastening eleven hog rings on its top side. First extract the seat frame module retaining screw and seat module if it exists before removing the seat trim cover combined with the pad and seat frame. You should remove the seat cover from the seat cushion followed by the seat cushion removal from the seat pan. Start by placing the seat cushion on the seat pan followed by attaching the seat cover to the cushion by moving it from side to side. Install the seat module when equipped with the retaining screw tightened to 5 N.m (44 lb in). First fasten the 11 hog rings to the cover and pad surface at the top section followed by installing the 2 hog rings at the bottom rear side of both components. Reengage the seat heater electrical connector as you join the seat cover hook and loop retaining strips before installing the seat electrical harness together with the SIR electrical harness onto the seat pan. The front/rear J strips and side J strips need installation before securement of the seat pan to the seat adjuster frame. Attach four retaining nuts to studs on the cushion underside while screwing them to 25 N.m (18 lb ft). Reinstall the 3 screws from the seat switch bezel.
