There is a flat screw cover that is set into the grip of the front doors on the inside. The one on my driver's side is missing and I'm trying to find the part online. Does anyone know where I can get it besides Toyota parts and service, or know what exactly it's called?? The photos are of the passenger door one, which is the only side that has it.
I think it's the switch bezel cover. $1.62 2010 Toyota Prius Parts - Camelback Toyota Parts - Genuine OEM Parts - Free Shipping
Take the one from the passenger's side, turn it over, and place it in the driver's side door. While you're still missing the passenger's side cover, it's out of sight and out of mind. Reconsider my remedy above.
Try another dealership? You could email a bunch of parts departments; wouldn't doubt someone will under bid that by about $10.
