Felt. But in truth, you might has well replace the vents. You’ll put more work in trying to fix them versus replacing. I had that same issue when I bought the truck. Spent a lot of time trying to fix, it can be tedious. I ended up getting new ones, and wished I had done that in the first place. They are so much cleaner and prettier now. And they stay in place like they should.
