Hello everyone,
No long ago, I found that the there was something happen on my exterior B-pillar trim of left rear door.
The corner on the exterior B-pillar trim of left rear door was a bit separated.
I don't have any idea that what causes this condition.
Does anybody know how to remove the exterior B pillar trim of rear door?
Thank you.

Part number 4 in diagram.
Doesn’t look like there’s much holding the top unless there’s some adhesive.
