I used too much force and the lower retainer metal clip, fell off. Now it's impossible to get the retainer clip back in position. So I just put the cover back on without the lower clip. Hope the seal is still ok.

Taking off bumper and wheel just to replace a light bulb?? what a disaster in engineering
