Factory part number 85524987: an upper side panel supplied by GM.
It is catalogued under Covers & Caps > Panels & Plates. Configuration note: Lower components.
A cap that vents and a cap that does not are visually similar, and swapping them gives a fault code or a pressure leak rather than a fit problem.
Leaves our US warehouse in one to two business days, and shipping is free over $59. The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it.
