Rear Passanger Door Water Leak! HELP!

Since this LA rain has been happening, I started to notice that my rear passenger side carpet was moist with water. I got the chance to investigate while it was raining and tried to track it down. To my surprise, after removing the cover molding near the bottom of the seat I notice that water was leaking in near the inner door seal.

Has anyone had this problem? Is there a fix to this? Not really planning on paying $95 for a new inner seal.

Your door seal looks dry and cracked, rub your seal generously with linseed oil or vase line to restore its flexibility, it helped mine after a few attempts.

OP, has the door card (the interior cover) ever been removed? There's a vapor barrier behind the door card. It may have been removed and improperly replaced. That'll cause leaks. Also, check the drain holes on the underside of the door. They could be clogged.

I did get my speakers change a while back.

Today I got the chance to remove my rear panel and the vapor barrier was seal properly and it was completely dry.




After putting back the rear panel on, I just lifted the inner sealed up and here's what I saw.




Does this mean I should might as well buy a new inner sealed?

Hmmmm. That foam cover may or may not be the vapor barrier!! That looks like a sound deadening layer. The vapor barrier is usually a fairly thick plastic sheet (thickness: at least 15 mil) that's attached to the door with some nasty black tar-like substance. As far as the gasket, it depends on where the broken section is located. If it's at the bottom I'd leave it perhaps with a bit of repair using RTV. These gasket are very expensive, btw.

What you have there is a vapour barrier. The vapour barrier may look fine. But did you run your fingers around the edge of it where its glued/sealed to the door. I'm betting that its not fastened all the way around your door as it my appear. Run your finger around it and see if you can pop it through anywhere
