    Stumped on a part number - door vapor barrier

    Vapor barrier, insulation panel...whatever it's called.

    When I removed my driver side door panel and vapor barrier to replace regulator and sliders, I tore the barrier in a couple spots and just figured I'd pop in a new one if reasonably priced.

    However, after browsing RealOEM for about 15 minutes, for the life of me I can't find the piece. I've looked under everything to do with doors, but no go. Anyone know a part number by chance?

    No biggie as I could probably repair what I've got, but I'm sort of OCD. It'd be nice to have an interior door handle again too.

    Edit: Wow, I'm an idiot. It's staring right at me in the first link.

    Carry on.

    Yeah, I figured that out 5 minutes after I posted. Palm to face. $37 on ECS. I can live with that.

    No, that's not your problem. Well, unless the door skin is missing!

    I don't know, I sort of know what he means. My DS door (without the barrier or door panel) seems to whistle and it's a heck of a lot noisier than it was with all that gear in place. But if it was whistling with everything installed, I'd probably recondition door seals as an easy starting point.

    No door panel is not at all the same thing as no vapour barrier! I'd certainly expect that to be noisier.

    It's been off for so long I think I'm just used to it now. Will be like a new car when I put it back together.
