Passenger Floorboard Leak

I know people have asked this question before, but I can not find the answer. I am getting drops of water while raining in the passenger floorboard. Can not find where it is coming from. Any help would be great..

I saved this post from awhile back, here you go:

Under the hood against the firewall there is a plastic duct, more than likely it is leaking by that. You will have to remove the coolant reservoir to get good acess to it. I sealed my with caulk and have had no trouble since then. It was pretty annoying to find.
