There are four drain holes under the cowl for water to drain out of that area. I have had my Crossfire for over ten years, inspect the drain holes when ever I'm under the cowl ( which isn't all that often, but I know all four drain clearly) and have NEVER had a problem with water entering my car through the A/C intake. You should check the drain holes in the center and the other at the drivers side. If the drains are all working you shouldn't have water entering through the A/C intake.
