MDX year 2012 model.
I have recently noticed a water leak marks on the speakers that are embedded in the body/side-panels by the 3rd row seat. Many posts ( Youtube and other internet sources) suggested that water leak might occur from the seals and hinges of the tailgate and body.
I thoroughly checked all the seals on the tailgate especially on the right side of the tailgate but that does not seem to be fix.
Where else should I investigate to find the source of the leak? I’ve attached a picture below. Thank you for your assistance
