seems I have a leak from underneath and its saturating the carpet psngr side rear... defiantely coming from underneath- and seems to be origniating from near the hump which separates the L/R side of the car. Are there any drain plugs or perhaps bolts that go through to the outside form underneath that might be leaking- i see the seat/seat belt is obviouosy bolted down - any advice is appreciated... 1999 well maintained Le Sabre- even has undercoating - I looked underneath but didnt see anything obvious.... thanks all!
