The cover ,as you say, is the one that you have pictured on the drivers side. This is an on going problem for all of us. If you stay of the forum , usually in the spring an fall , you will see members reminding each other , time to clean out under the cowl. There are drainage tubes in there that carry water out. When they clog up , most times, it runs in an floods the passenger floorboard causing numerous problems. I'm glad you got on this before an further damage was caused.
