Stupid fastner question.

[CMF_queazocotal]

I've broken several fastners that hold bits of the interior trim on (notably the trim behind the central pillar, over the ECU and the wheel arch liners).

These are black, ~20mm diameter, with a rounded head, and a 6mm diameter 1mm depression in the middle.
I don't know what the back of them looks like, as I have not successfully removed them.
What's the correct procedure for removing these, and what are they called, so I can track some down.

I just yank them out. Gently... sometimes with a flathead scren driver for leverage.
No idea what theyre called... Take one out and take it to your autoshop. They might know. Or even to a nissan workshop.
If you find out where to get em and what theyre called, i need some too

Same as those little black plastic things on the rear hatch?

They're called scrivets.

i think your talking about the ones that you actually push in the centre part in, then grab the outer and pull it out together. i accidentall pulled one out like that, then discovered thats how they work. I need about 7 replacements though

Sigh.
I assumed that after I ran the pressure washer over the thing, that it'd be clean.
That combined with poor visibility must have meant that I missed the screwhead in all three cases.
Oh well.
Thanks!
