I read a little about this by searching, some have mentioned this can occur because of rear window gaskets and others have mentioned the third brake light gasket.

What you guys think, kinda annoying.

 

my guess is brake light

 

What he said ^^^^^

Just take it off and RTV it up. Just remember a little bit goes a long way. Or the dealer should be able to replace the seal.

 

Being an 08...id let the dealer do it.

 

The dealer has managed to make a mess of everything and lag on repairs.

If there is a simple fix, id rather do it myself. Is the suggestion a new gasket or take the current one out and RTV it ?

clear silicone is the way to go

 

EXACTLY!

One of my wife's favorite words while she's on the phone!..lol

 

i was having this problem a few weeks ago. hasnt been happening much. i got thr rtv sealant just havent had a chance to seal it up yet. weird it only happens sometimes. it could be raining very hard and i wont get anything. but then it could be misting and i will get it coming in. its weird. but im almost positve its the third brake light too.

 

Today i purchased some clear sealant and opened up the third lamp and i am a bit confused. Behind the third lamp is metal and maybe 2 inches above that is a hole for the wire. I don't see how even if water got in here it would ever get in ?

Maybe someone can clarify ?

My Gen 2 RCSB did this. I removed the CHMSL and silicone-sealed the unit. Nary a drop after that.
