Very easy DIY

In this video, you can see that there are actually 2 separate doors in 2 different parts of the dash.



This guy didn't initially realize that he had to fix both doors. He did the fix in two 996 in the video.

door accessible from the frunk
car #1


car #2


And then in car #2, this is the door accessible by going through the stereo hole and cutting a hole in the ducting.
