Dirty carpet 2005 Chevrolet Impala passenger side rear
The carpet has a dirt stain that keeps growing! No one has sat there in years,
and I haven't spilled anything back there, but this stain will not go away. I did
find the rubber gasket under the rain cowl was mostly off, put it back on. The
floor board is not WET. Just this mystery dirt that grows from the size of a
small spot to almost covering the floor board there!! Anyone else have this
problem?
