Let me tell you a little story. I picked up my car new in July of 09. I got it home and gave her a good wash. As I was drying out the underside of the hood and radiator bulkhead, I noticed a little water on my drivers side fuze center. I went to dry it off and the whole cover moved. I lifted it up and saw a whole lot of water inside the fuzes and stuff. I took the sub-cover off and there was water everywhere. I took everything out and totally dried out all I could reach, then put all the fuzes and relays back in place. I ran the car with full heat and A/C (the box is vented from the cabin to keep it cooler than the engine compartment) and I let it totally dry out. I made sure it was all completely dried out and then placed the cover back on. Thats when I noticed the cover locks into the rear first then the front snaps in place. Ever since then I make sure no water gets in there and check it after I dry out the engine area the best I can. I have never seen another drop of water inside there but can only wonder how many times the car was washed at the dealership before I bought it with that cover misplaced. People, check and make sure your electrical covers arer properly placed, so that no water can get down where it doesn't belong.
