I have a 2002 with a factory sunroof. I noticed that I have wet carpet on the passenger side under the floor mat after a hard rain. I looked everywhere, but I have discovered the problem but I don't know how to fix it. It is the front drain line. When I pour water down the drain line on the sunroof it comes out the drain in the panel next to the door hinge, but it also drains inside the car. Any solutions? Should I just plug the hole and hope that any water finds another exit?
