I have the same issue. 3 years ago, my heater core was leaking into the passenger area of my Jeep. I used some stop leak and the problem was fixed. However, now I get the same kind of rattle you do when I'm running the heat. So I have a feeling my heater core or blower motor is about to crap out. You may be having the same issue. Are you sure it's water coming in and not antifreeze? Does this happen when u don't run the heat? Are you getting any other symptoms? Everything on mine works just fine, just hear a little rattle in the dash every now and then, but no leaks.
