Crackling coming from front vent.

[Crispystork]

981 Boxster GTS.. theres a faint crackling sound coming from the front right vent under the window.

It's definitely the one on the right. It doesn't get louder when you drive, but then it doesn't get louder when you turn the fan up.

Anyone else had the same?

Yes! Was a leaf stuck between inner and outer wing.

Sounds like a dry dead leaf has found its way in..
