Hey guys, I've got a 97 XLT long cab/bed that has developed the most horrendous sound inside the cab. It's coming from somewhere on the passenger side and I cannot reliably reproduce the sound, or determine where exactly it's coming from. It sounds like maybe it's coming from the passenger door, pillar, or glovebox area. I've removed the pillar, door panel, glove box, and done everything I can to figure out what the noise is. It sounds like two pieces of styrofoam or plastic rubbing together and it's loud. It's way more than just a rattle because even with music playing and the window down, I can still hear it over everything. I even took a rubber mallet and went around trying to see if I could recreate the sound; no luck.
Any ideas?
