The problem is there is a pool of water in the passenger side foot well from all the rain here is Seattle.

I took the cowl off and there was no blockage. The hole for the blower motor does look like there should be a cover. So I made one out of plexiglass, weather seal, and a lot of duct tape. I also removed a rubber thing from the wall separating the right side drain.

I had to drill holes on the top of the plexiglass because the blower motor can't suck in any air. Now there is no water getting in, but it creates another problem. Apparently covering the hole for the blower motor also keeps all the hot air inside the car. When I turn off the car and leave it alone for awhile, it steams up my windshield and windows and they collect water vapor.

The next time want to drive, I have to wipe them down with paper towel, because turning up the heat and fan wont do the trick.

But hey, it beats a pool of water in the car. Time to design a new cover.
