I have a 2007 ford ranger Fx4 level 2
There is water somehow leaking into the to passenger door panel and I am wanting to know if anybody knows how it's happening? I have unplugged the drain holes to let it leak but it's still filling. Where or how could water be getting in?

 

you can't really prevent water from getting in the door, that's why there are drain holes in the bottom. You should consider removing the door panel and cleaning out the debris that is clogging the drain holes. Probably what is happening is when you clear the drain, you are displacing the debris, but it is clogging the holes again when water starts flowing.

 

+1 ^^^
Water will always run down the window and into the door, forever

Yes, remove door panel and vacuum out any debris
Add more drain holes if you want

 

I did what Ron suggested and drilled extra drain holes. As long as the water is never sitting in the door it's fine. Clean and let it drain free...
