I just dont think water is getting in there though.

Instead the water is draining into the blower motor area and then onto your floor. This is a common problem, exactly the same thing happened to me. Installing the deflector is easy and its cheap. Hit me up once you get one I can give you more instsllation info.
Wow kzoo? Your the closes to me that ive seen on here lol. What kind of grand prix you got?

Anways, i dont think its that though. As i said above, theres nothing wet when i check the blower motor and its still a bit dusty, no moisture or anything so it cant be that.

It has been rainy here all day also. After i cleaned up, it was still raining and i didnt see any water leaking through hours later.
