Does anyone know how to tighten the little plastic holder for the driver's visor? It's a little loose. I see a small opening on the side facing the windshield, but I can't seem to see any screws. The dealer said it was simple to do although he said he'd need the car for 2 hours because they were slammed. I'm hoping I can just do it myself. Any help will be much appreciated.

 

anybody have ideas for this one?
