Water leaking in dripping out of body

The last few days I’ve noticed odd wet spots as I come out to my truck. I finally got a chance to try to track it down. The water appears to be coming in through the rear passenger door. It’s seeping out of the body of the truck.

I know it’s normal for a certain amount of water to leak into the door. Do I have a drain blocked somewhere or which weather seals do I need to replace? Nothing seemed out of place. I appreciate any input. See pictures below

 

I’m an idiot. I was at work when I posted that. It made no sense where the fluid was coming from. I had a new pint of brake fluid in the door that developed a hole and started leaking. Hoping it doesn’t destroy the paint and cause me rust issues. ‍♂️

 

Glad you got it tracked down. I was going to say that I would suspect rain running down the small void where the door opens, runs down until it hits the bottom, and then runs out. But, I like your answer better!

 

Wash off the BF ASAP. It will cause your paint to bubble up and come off.

 

That sucks, use dawn dish soap to wash it off and if you want to help protect from corrosion this stuff is great.
