Dashboard vents replacement parts

Anyone know where to find replacement defroster vents? The plastic covers that direct the defrosting air onto the window on top the dashboard.

2000 blazer, 4 door, light gray.

Or the proper names for them?

I'm sure they're part of the "whole dashboard" if I ask the dealer, but they come right off (after the glue has broken down over the years) and are cracked beyond repair from sun.

Glued them back together for years, but they're just too deformed now to stay in place or go together.

Thanks,
Brian

I have the same issue. I just glued mine for the first time the other day. The problem I have is that my Bravada has a sensor in it. That part pulls right out. I'ts not part of the dash.

Just curious as to what kind of glue you guys used. Was it any super glue or something specifically for plastic parts like model glue.

I used crazy glue. It worked good for me.
