water pooling inside door panel
 

I have a 4-door 2006 Mazda 3 and noticed that water is pooling inside one of the rear doors. When I open the door water slowly drips out from around the seal at the bottom. Im guessing its a broken seal somewhere (maybe around the window although if it is, its not obvious where) that is allowing the water to get in. My question is how would I go about getting the water out? There doesn't seem to be a drain plug. I could remove the door panel and look for other solutions but is that even worth it? Maybe someone else has experienced this?

i have an 04 mazda3 hatch and in the bottom of all the doors there are small flaps with holes behind them maybe look at yours and see if there are some there maybe theyre plugged
