Q: How to Replace a Rear Seat Cushion Pad and Cover on GMC Envoy?
A: First remove the vehicle seat cushion before removing the seat cushion bracket to change the rear seat cushion pad and cover. Before proceeding move on to remove the seat latch bezels while using the Clip Removal Tool (J 36796) to disconnect push pins beneath the seat bottom and begin the seat cushion extraction. You must expose the J-strips on the carpeted section to unfasten the seat cover from its seat pan position. The foam can be compressed beginning from any forward corner to partially disengage the seat cover assembly from the seat pan but you should avoid pulling adhesive-backed strip from the seat pad when separating seat cover retaining strips. You should separate the retaining strips to remove the cover followed by extracting the cushion and cover assembly off the seat pan. Once the reinforcement bar has been released from its hog-ring position you can detach the cover from both the cushion and the bar itself. Security begins by connecting the cover to the cushion before refitting the reinforcement bar to its place on the hog-rings and lastly applying the retaining strips which secure the cover to the cushion. Install the seat cushion to the seat pan by setting the seat pan over the cushion and cover assembly while slightly compressing the foam until you attach and position the seat cover and cushion on the seat pan. Plug in the J-strips which attach the cover to the seat pan and reinstall the push pins located underneath the seat bottom before installing the latch bezels. Reattach the seat cushion bracket before returning the upholstery to its appropriate position in the vehicle.
Q: How to replace the front seat cushion pad and cover on GMC Canyon?
A: The replacement process for front seat cushion cover and pad requires the vehicle seat removal followed by cup holder bracket detachment through straight pulling. You need to remove first the trim panel from the front seat cushion exterior before detaching the 3 bolts securing the cup holder bracket from the seat frame except in cases with no cup holder. Unclip the front, rear and side j-strips (1, 2) which are located under the seat before pulling the lumbar knob directly off while accounting for an equipped seat. First remove both the seat switch bezel (if present) while simultaneously taking off the recliner handle. Unlock the seat recliner from its seat adjuster mounting with two bolts and then separate the seat back unit from the seat cushion unit. After disconnecting the seat belt buckle electrical connector the technician should detach any clips or straps that hold the electrical harness to the seat cushion frame base. Disassemble the seat by removing the bolt that fastens the seat belt buckle assembly to the seat adjuster then unfasten the seat cushion cover and cushion foam. Before pad replacement you need to peel off the heating element from the pad when the pad contains this component. Installation requires an adhesive-backed heating element which should be applied onto the pad when replacing (if equipped) after which the cover needs to be installed onto the pad through hog ring attachment. Install the seat belt buckle assembly through the Seat Cushion Pad while attaching the frame to the seat cushion foam pad along with its cover. Attaching the seat belt buckle assembly to the seat adjuster requires fastening it with the bolt until it reaches 55 n.m (41 lb ft) torque. The seat belt buckle electrical connector should be connected and all electrical harness clips or straps need to be restated. Fasten the seat back assembly to the seat cushion assembly using the 2 seat recliner bolts while torquing them to 24 n.m (18 lb ft). If the seat has a switch bezel you should reinstall it before pushing a lumbar knob directly onto the shaft when present. After installing the recliner handle you must attach the front and rear and side j-strips (1, 2) under the seat platform. Use three bolts to fasten the cup holder bracket onto the seat frame while tightening them at 9.1 n.m (80 lb in). Then install the front seat cushion outer trim panel. The seat installation procedure finishes with the cup holder direct installation on its bracket along with the seat reinstallation into the vehicle.
Q: How to replace the front seat back cover and Seat Cushion Pad on GMC Sierra 1500?
A: The process of replacing the front seat back cover and pad requires the removal of the head restraint and seat trim panel followed by the lower Seat Belt anchor nut before disengaging the j-strip retainer at the bottom of the seat back cover and disconnecting the heater seat element connector if present. The armrest should be removed before lifting the seat cover over the air bag cover until you reach the top seating position. The bottom end of your seat back cover has a j-strip retainer which needs uninstallation followed by disconnecting all heater seats elements connectors if they exist. You should lift the seat back cover half off its foam pad to access the armrest clip along with the armrest (if equipped). Push a flat-bladed tool beneath the seat cover to slide it over the air bag cover before carrying out the seat cover removal up to the seat top. Remove the rear cardboard panel by disengaging its panel fasteners and release the head restraint retainers by unclipping them. You should remove the bolts that secure the Seat Belt tower cover before removing the cover from its position. Feed the Seat Belt along with the Seat Belt bezel through the seat cover opening before lifting the rest of the cover from the foam pad until the pad can be removed from the frame. Install the Seat Belt tower by affixing the foam pad on the frame first and then tighten the Seat Belt tower cover bolts to 1.9 n.m (17 lb in). After placing the rear cardboard panel and hooking its fasteners the seat back cover needs to be partially installed onto the frame top. After routing the Seat Belt and its bezel through the tower opening users must mount the armrest clip then gently pull the remaining cover portion using alternating side-to-side movements of the hand. Install the armrests and head restraint retainers before fitting the seat cover around the air bag cover and inserting the nut onto the lower Seat Belt anchor while tightening it to 53 n.m (39 lb ft). You need to put the seat trim panel in position and install the head restraints before pushing the seat cover down to check it has secure retention from the velcro in the seat cushion and to join the j-strip at seat bottom.
