1999 Blazer-I need help finding a replacement for the black plastic between the drivers door panel and the door. For some reason, mine fell into pieces when I pulled the door panel off. My toughest challenge is knowing what it's called. I've seen it referred to as a splash guard, a water shield and a sound barrier. Any help finding a replacement for it or nomenclature would be much appreciated.

You can browse according to your vehicle and find out what the part is.

Another way is to look on the broken plastic parts if you can find the OEM or GM parts number.

Or post a pic of the part or where it goes on the door. Somebody here should be able to point you in the right direction.

 

I used visqueen and cut my own.
