The drain isn't directly accessible from under the hood. You need to remove the plastic cowl at the base of the windshield. Remove wiper arms & 7 torx bolts, lift up the cowl & gave a look below the passenger side hood hinge - if yours is like mine was it's plugged with dead leaves etc. Search for siren removal for cowl removal procedure & pics - that's what I was doing to get me into the right area.
