Yep, where your feet are if you sit in the back seat. Just open the rear door and stick your head down there, you'll see them. Though you may need a flashlight.

I've been digging around in there for ages with a magnet tool. Is it all one big chamber? Haha I feel like an idiot.

Yea it's all just one big open plastic duct. Maybe you dropped it between the soundproofing and the floor pan. I've done that one too.

I guess I'll keep fishing. I've just finished applying aluminium tape to the blend doors. This DIY was very helpful, thanks guys!
