Noise located,what is it?

[Petrance]

Short story,i was hearing a noise,(i thought) from the dash.like a screw going all over the place.after many attempts to locate the noise and disassembly the dash 2 times,i went to a buddy of mine to look at it.after many hours he located the noise inside the air duct under the passenger front seat.now im wondering what is this that he found.i will post some pictures. 334530874_119736811027134_5486514173214201459_n.jpg334483974_1605660829911653_4922506614039775078_n.jpg334483048_609428007305136_6298278735872618261_n.jpg

So in tube 22. Maybe it got kicked up into there by a back seat whoever. If it did come from the forward direction, maybe some part from the air box:

Hopefully it's not some pin for a motor arm linkage or such.

thanks for your reply.it started randomly one day.do you think i will have a problem?for its size is really heavy,so im guessing is doing something important :/

If it's heavy, I assume it's metal then instead of plastic?
No idea, not sure what it might be.
If nothing is operating wrong, then seems to be all good. But if you start getting something odd with the climate system, keep this in mind.

I Cant tell for sure the material.is like metal mixed with plastic.i dont know.so far nothing wrong

Looks like a bike cable ferrule but without the hole. My guess is it is some sort of tube/cable housing end piece. I wouldn't be too worried if everything else in the car is functioning normally. It could have simply been debris that made its way down there from who knows what/where.

At least the noise is gone!
