Water inside the door?!
As I stated in the build/journal thread for my car, it isn't garage kept. Today when I got in it to take my daughter to school, her door made a loud sloshing noise when she closed it.
The car hasn't been driven in about a week because its been detailed and its rained several days. So I keep the car off the roads when it's like that if I can
Anyways, I don't ever remember hearing this and the car was painted not long ago. I'm not sure what's changed but something has.
I just took the paneling off the door and it's got a bunch of water sitting in the bottom of it.
Other than removing the water what should i do? Do I drill a small hole on the bottom? What exactly is causing this?
Thanks in advance

Clean the trash out of the existing drain holes. There are about 3 oval holes with rubber plugs that block most of the hole, plus a smaller hole at the front and another at the back. In a perfect world, the weatherstripping keeps MOST of the water out of the door, the rest runs down and drains out the bottom.

I didn't realize there were drain holes in there. Makes sense

Interesting sound, isn't it? Close the door and hear whoosh - whoosh. I hope my door doesn't rust away now.

The orange bits are probably what's left of the adhesive deadener that was injected between the impact bar and the door skin. It tends to give up on early-mid thirdgens.
It's important to keep the drain holes clean. Otherwise the water can't get out and the door will rust.
The same applies for the drains along the rocker panels, in the quarters, around the cowl, between the lower fenders and body, etc.
Most people don't realize the plastic moisture guards between the door panels and the door help direct moisture inside the door directly into the drains, and the keep the door panels from getting wet and damaged. Make sure they're in place, and the tabs across the bottom are tucked into the holes in the inner door.
