Leaking front sunroof drains - can't find the connection

[skorpiius]

From reading all of the posts in the past it sounds like leaking front sunroof drains is either the tubes disconnect from the sunroof tray, or the connection between the downtube from the tray and the tube that exits the car gets detached. From what I can tell the latter is my problem as there is no water running down the inside of the A pillar when I test.

I believe the connection is behind this black rubber membrane but after using a borescope and my hand I can't see nor feel anything. Can anyone give me some guidance on where exactly behind this membrane the connection is? This is the passenger side footwell





Thanks

If i am not mistaking connection goes behind the a pillar down
