I've not been able to install carpet because I have a leak somewhere. When I wash my car or it rains I get a small amount of water in the passengers foot well, none on the drivers side. I have recently removed my old carpet and repaired a couple of rust spots in that same area. If the sunroof drains were clogged it would leak through my headliner, right. I mean I can see a few drops of water comeing from under the glovebox area. I am NOT going to cultivate any more rust on this car so I have to get this figured out. Aren't there drains somewhere in the plastic grills below the windshield? Would those cause a leak inside the car?? Thanks for any suggestions.
