2008 Chevrolet Cobalt Q&A
2008 Chevrolet Cobalt Question: Why is my 2008 Chevy Cobalt leaking water in the front floorboards?
first thing to do is see if its under factory warranty still if it is then have the service dept fix it. if not then it sounds like you have a drain problem causing to leak into cabin from heater core - W.Fields
Bought car in June 2009. In last few months, when we have heavy rain, water is standing in front floorboards next morning. Nothing else is wet.
