Okay, i had to rip apart my doors today to fix a problem with my power windows (sticking), and i encountered some kind of barrier. I'm not sure if it was a moisture barrier or what, but i've never seen this on a car before. After the door panels were removed i found the door to basically be covered by a clear plasict piece secured by what looks to be silicone. Is this some kind of moisture barrier or something, because if it is it wouldn't do a very good job (wasn't even sealed all the way around).

What do you guys think?

Yup. I'm not sure if its silicone or not. After years and years it still stays sticky.....I got some in my hair today after working on a honda.

mu guess is that it prevents wind goin into the car i ripped myn out and now i get cold air through the door

I'm sure it insulates sound slightly too.

Eple

yeah..i ripped mine out too, now i'm wondering if i should put a new set on or something..

IIRC the backside of the door panel is bare particle board, which is not moisture friendly. Without that plastic barrier it could warp.

that's why its called a moisture barrier. and the adhesive should be reusable. just carefully peel the plastic off and stick it back on when your done. Just don't look too close inside the door or you might land your head in the goo.

if you live in B.C. i would put something back in, i ripped mine out and i have a tempary garbage bag tapped in there until i fix my regulators (which i have tried for hours doing many things). Iam glad though the the people i rent my garage off of left alot of that this plastin in there and Iam sure they wont know if i take a couple huge chunks

Moisture, dust and air barrier, reinstall it or make a new one out of heavy plastic, 6 mil will work. I use the aluminum tape for ductwork when I reinstall mine. It is one of the few tapes that have an adhesive that will cope with time and temperature changes.

I think it's more to keep excess dirt out.

that sounds like a good plan, i'll do that once my windows are completely fixed (i did a temp repair on them, i need to get back at them in a few weeks).
