Your 2002 has the old rubber seal that tends to fall off and cause the water in the floorboard issue. I would suggest at least pulling the cowl and gluing it in place BEFORE you have a problem (or replace it with the revised part) just to nip water, and blower motor failure from the water, in the bud. Your 2006 may or may not have the new part already. I have found that 2004-2007 Grand Prixs occasionally have the new one already in place. Most don't, but for some reason it's kinda spotty on those years. 2008+ w-bodies should all have the new deflector already.
