Water in the doors?

Just started a speaker upgrade in a 2023 DCOR and noticed some wetness inside the doors when I pulled off the panels and went to start installing sound deadening material. It’s not crazy, but there’s definitely a little bit of water. I live near Seattle, and it’s definitely been raining hard lately, but this is not something I expected. It’s all behind the vapor barrier/between the inner and outer steel skin. I found it on both front doors, but not on the back doors. It looks like there is a small drainage hole at the bottom of the door that communicates with the area between the inner and outer metal… I imagine this is intended as a way to prevent any substantial water accumulation, and what I am seeing is just condensation, but wondering if anyone else has seen this. Is there a concern for rusting out? Or is this totally normal, and nothing to be concerned about?

 

Normal and designed that way. The water/humidity that makes it past the window seals needs an exit route.

Don't block the drain holes when soundproofing.

 

Normal. My F150 had enough water in the doors to where it would slosh when you opened it! It's aluminum so I don't have to worry about rust but still a normal thing on vehicles.
