This is driving me nuts but also is somewhat humorous. Late last year on my 380SE I started to hear noise from dash on drivers side. It sounds like paper crumbling or like rain drops hitting the windshield. Also has been described as sound of "mexican jumping beans". I checked out air intake area below windshield for twigs, leafs, etc. see nothing. Removed under dash cover and cannot see anything loose. Removed dash speaker grille and speaker and cannot see anything loose. I thought it might be loose insulation or material on climate control flaps or something along those lines. Noise is there with climate control on or off

Sometimes it goes away and since we have had a lot of rain these last few days the noise is gone. ( Maybe humidity is playing role here) I don't know where else to look and when noise is evident it seems to be coming right by or very near the driver side dash speaker. The car is so solid and quiet when noise is gone so this is becoming obsession to fix

Anyone else have nagging noise issues similar to this?
