I have discovered a moldy section of carpet extending from the rear door
pillar downwards both into the rear door well and the back cargo area in
my 300 Wagon.
I am puzzled where this is coming from, the seals seem good on the
windows (though I am no expert), where else could the moisture be
getting in? Sunroof and along the headliner? roof rack? window seal?
Any methodical trouble shooting tips for tracking this down?
