theres a 'light clunk' sound coming from the rear when i close the passenger doors. im guessing it has to do with the pressure as all the windows are up.

There are vent baffles back there for cabin pressure and open when you close the door IIRC.

WRD4chano

so the noise is normal, thanks!

Acrad

Correct. Normal.

So there is an electric motor for this?

Never heard this but I have many years of loud music and work related sounds that have deteriorated my hearing

Acrad

Not electric

I haven’t looked at mechanism closely but if you play with rear doors opening and closing you can hear them flap. I think actually fairly common on most cars these days, Seen a few on GXOR going through deep water experiencing leaks through these vents... in addition heard some suspect exhaust smells come through these baffle/vents.

So the cabin air pressure opens and closes these vents. I don't recall these and never saw a moving vent while playing around with my rear Mods.

Acrad

I will try to post more info on these. On mine anyway.. If you open/close rear doors with like just a couple inches you can hear them

WRD4chano

well do you hear them when you close your doors? the noise im hearing is coming from the extact location highlighted in the diagram.

tecman

No I never noticed this.
