I need to remove my melted windshield spray nozzles from my hood. I can't seem to figure out how to remove the hood liner insulation on my '03 9-5 Aero to get access to the spray nozzles. I have the large plastic fasteners that have the small hole in the center holding the liner. I saw some other posts saying you just press into it with a small allen wrench, but I had no success with this. It didn't seem like I was doing anything except pressing the clip in harder . . . nothing was releasing. WIS shows that there is a tool that can be used to remove it; it basically looks like a small wedge. I don't want to tear the liner or destroy a bunch of these clips, so any advice or more detail on how to remove these fasteners would be much appreciated.
