Dropped it off tonight and hope to know something within the next couple of days.

Did you make sure to seal around the wire hole grommets UNDER the marker lights? This is usually where the water gets in and runs down the door columns and reaches the carpet. Just sealing around the marker light gaskets usually doesn't fix the problem. At least it didn't fix it for me.
