Work Procedure:
First determine which type of seat is in the vehicle. For a manual adjusted seat, perform steps 1, 2, and 3. For an electrically adjusted seat, perform steps 2, 3, and 4. The seat must be moved in its upper most position before it is removed. Once the seat is removed, remove the seat cushion carrier.
Do not disassemble the cushion carrier with the seat cushion and the wiring harnesses any further.
1. Clicking noise during manual seat fore and aft adjustment.
Cause: The engaged plastic parts (arrows, figure 1) in the fore and aft adjusting liver brush against the seat frame during seat adjustment with the seat is at its lowest setting.
Repair: Slant both of the plastic clips on the seat rail side with a knife of side cutters (arrow, figure 2).
2. Clicking noise when cornering (load shift) or when changing the seat position.
Cause: When changing the seat position, the cushion carrier brushes against the seat frame (arrow, figure 3). The seat is at its lowest setting.
Repair: Grind down the left and right corners of the cushion carrier by approximately 2 to 3 mm with a grinder or file (arrow, figure 4).
3. Clicking noise when entering and/or leaving, load shift.
Cause: A small clearance (play) is present between the cushion carrier and the seat frame in the center of the seat frame. When a load is applied, the cushion carrier and the seat frame come into contact.
Repair: Affix a self-adhesive felt strip in the center on both the right and left seat frames (arrow, figure 5). To do so, cut the felt strip to a length of 150 mm. Affix at a distance of approximately 180 mm from the front edge of the seat frame.
4. Clicking noise at the lowest seat setting.
Cause: if the seat height is set to the lowest position at the rear, the seat frame come into contact with the seat rail fastening screws located on the door side of the seat when subjected to load (arrow, figure 6).
Repair: Affix a felt strip to both of the rear seat rail fastening screws on the door side (arrow, figure 6). To do so, cut the felt strip to a length of approximately 50 mm.
