2005 Monte SS Water in Passenger Door
 

Does anybody have any idea as to why I would get a puddle of rain in my passenger door after a storm? I guess some rain is normal but this is a lot of water..it sloshes around in there..I am going to check the door drains but even so I dont think this much water should get into a door..Thanks for any help..

Your door drain plugged up. That amount is normal given the circumstances. Several people whose drains clogged noticed sloshing sounds. You'll even notice rust forming near the bottom if you leave it too long. Clear the block from the door drain and you'll be fine.

You may want to check the seals by the windows and make sure they are tight to the glass .
