Info - OnStar Module Cover Retaining Tab Breaking

The OnStar® module, located under the passenger side rear seat, has a protective cover. If the module requires service, the retaining clips of the cover may become damaged when the cover is removed or reinstalled.

When reinstalling the cover, it is suggested the following procedure be used.

1. Position the cover in the correct position over the OnStar® module and bracket assembly.
2. Using a 3.57 mm (9/64 in) drill bit, drill a hole for a retaining screw in the two front corners of the cover flange and the bracket assembly.
3. Install a self-tapping screw into the holes just drilled. The suggested screw is P/N 11516629. This is a black, Phillips head screw with washer head (4.1 X 1.4 X 16). Tighten the screw until fully driven, seated and not stripped.

Parts are currently available from GMSPO. This is a commonly used fastener. No special orders are required.
