2013 Mustang Convertible Water Sloshing
Every time after it rains or going through a car wash
I hear sloshing coming from the back right of the
car. Sounds like it is right behind the right rear
speaker. The water stays there for a number of days
and I think something may be clogged. Should I
worry about this water freezing in the winter? How
can I check to see if it is clogged and fix it?
