Location and Function

This panel mounts inside the passenger compartment on the upper right B-pillar—the upright body section between the front and rear passenger-side doors. It finishes the interior around the front passenger shoulder-belt area and meets the surrounding interior trim. Its purpose is to cover the pillar’s interior surface and provide a coordinated factory appearance while accommodating the seat belt’s passage through the panel.

3. Follow GM’s specified Supplemental Inflatable Restraint (SIR) disabling procedure before disturbing pillar trim.

7. Release the upper panel’s attachments carefully and feed the seat belt through the panel to remove it.

8. Compare the replacement panel’s mounting points and belt opening with the removed panel.

9. Feed the belt through the replacement panel without twisting it, then align and secure the panel.

10. Reinstall removed hardware and surrounding trim, following GM’s torque specifications and fastener replacement requirements.
