Rear Footwell Wet (Insert Drain Path)

Some customers may comment that the rear floor is wet.

When the vehicle is parked nose down on a steep incline, during a hard or prolonged rain, water may accumulate in the front seat belt retractor area. This could result in flooding over the poured-in-place foam and then into the passenger compartment.

Add the drain path, using the following procedure:

1. Remove the RH and LH rear quarter trim panels.
2. Remove the RH and LH lower seat belt retractor bolts and set the retractor aside.
3. See the figure for approximate locations for the 10 mm (3/8 in.) drain holes in the foam. Hole location is critical.
4. Install a drill stop placed approximately 32 mm (1¼ in.) from the end of a 3/8 drill bit.
5. Install a drill bit in a 90° degree angle drill for better clearance and drill the holes on the marks, as shown in the figure.
6. Vacuum up the foam and metal chips.
7. After drilling the holes, it is important that the appropriate anti-corrosion primer be applied. Refer to GM Approved Refinish Materials Booklet (GM4901M-D-99) for additional information.
8. Repeat for the other side.
9. Reinstall the seat belt retractors.
10. Reinstall both quarter trim panels.
