Got a 2008 Chevy Impala with 44 380 miles. It's Automatic
Got this knocking sound that comes out of the AC blower..
Wondering what the problem could be. It kind of comes and goes.. and when I turn down or off the AC the mouse goes away, but sometimes even when the AC is off, there's still that knocking sound.
Can you make a YouTube video of the noise & post the link here?

It might be ghosts trying to escape..
If not, it’s just a common Impala problem -

Could be some junk lodged in the fan housing or the slot for the cabin filter.
