I have a major leak somewhere that is leaving a big puddle, nee a minor
lake, on the floor by my right rear passenger in my 1987 Audi Coupe GT.
Nothing else is wet. Not the upholstery, not the side panels, not the
roof panel. It collects during rain, and a friend thins it is a clogged
gutter that apparently helps drain water away from the sunroof... a
gutter that supposedly travels inside the body of the car. Does anyone
have any idea for me to diagnose and fix this problem? Please advise
soon. Thanks...
