I can see a faint outline of the hole! You have great eyes!
I punched around in that area (drivers side), and I can see what seems to be the hole. Whatever plugged it up is tough. I wouldn't want to hit the center punch as hard as I had to, if I wasn't pretty certain it was there. It's hard to open, but I suppose it doesn't have to be perfect. I think I have it located on the passenger side, too.
