There is a small gray round "plug" thing when you look at the back of this assembly. I am sure it has to do with letting air in / out of this assembly, to prevent moisture build up inside, how does it work?
I looked at one very closely and I can't see any kind of hole in it? I checked one that never got moisture in it and like I said, no hole??? So how does it work?
Also, I have had issues with this assembly only on the driver side, getting moisture in it. I purchased a second new one and it too got moisture in it within two weeks.
I had replaced them because the originals were "gone" no good anymore.
The first new one that got moisture in it I checked for leaks but found none.
Any ideas why two have this problem?
the inside gets "frosted over " with moisture. New one on passenger side, same brand is OK.
