You've got to be kidding me. I am trying to drop the engine in my car and I get stuck on this problem. I can't get the fuse box cover panel off. The upper plastic nut just turns and nothing happens because it is spinning free of screw that is supposed to grab on to. No I am going to have to destroy that upper plastic nut somehow and dremel off the head of the screw.

Believe me, that is only way to do it. I did it.

I dremeled the plastic nut off the screw. Then I use a pair of needle nose vice grips to turn the screw and that worked. Thx.

The top fuse box cover screw is what gave me problems. Here is a photo of screw in place after I took the black plastic head off the screw. I then used needle nose vice grips to unscrew it carefully.

The other photo shows a good screw from one of the other two corners.

The brass insert is spinning in the base of the fuse box. I had the same thing happen.

All you had to do is pull the cover off (after loosening the other screws that could be loosened), unscrew the insert and glue it in place in the fuse box.

On my 964, I experienced both the spinning insert in the base as well as the spinning plastic head - both on the same screw! Thankfully, Alex's approach (Pull!) worked on this insert and a pair of Vice Grips held the head well enough to unscrew it from the insert.

However, a second insert refused to budge. I had to Dremel the plastic and metal head of the screw and drill the screw. Once enough of the screw was drilled, I was able to get the top off. The screw itself was loose in the insert by this time, likely due to the heat generated by the drill bit. The good news is that I did not damage the top. Now to replace the bad screws with bolts and glue the insert in place.
