Nissan Titan 2012 model the passenger side front door continues to fill with water even when it doesn't rain. Per research if the floor board was wet on the passenger side it would be a clogged drain however the floor board is dry.
When I research to see if the door has a drain I'm unable to find any results. When reviewing the seals they look to be fine, no damage and door has never been wrecked per my understanding and just has started doing it within last month.
What would cause the door to fill with water and what should I do resolve it? Is this a standard issue and I just have a clogged drain in the door?
When you open the door you can hear it swoosh around. After opening and swinging water will slowly leak out. Hope that helps because I've been unsuccessful in finding any results.
