DEAR TOM AND RAY: I bought a 2006 Pontiac GTO about a year ago. After a considerable search, I found one with an aftermarket sunroof so the sun’s rays could help heal the psoriasis problem on top of my head. When it rains, or when I go to the carwash, my car fills with water. It sounds like there is water sloshing around inside the passenger door. During heavy rain or while driving at high speeds on a wet freeway, the rear passenger floor gets absolutely soaked. The water then moves forward to “dampen” the front passenger floor. I know what you’re going to say: “Replace/repair the sunroof first.” OK, I will. But just in case, what else could it be? Thanks in advance for your help. — “Bathing Bill”
RAY: We can give you a couple of ideas, Bill.
TOM: That water that sounds like it’s sloshing around in the passenger door? It could be sloshing around in your passenger door!
RAY: Water can get into the doors when it rains. That’s why doors have drain holes at the bottom — so the water can get out. But if your drain holes are plugged up with leaves, dirt or dead insect carcasses, water could be accumulating in there. And if a few inches of water builds up in the door, it easily could spill over onto the floor of the passenger compartment.
TOM: So have someone check the drain holes in your doors for you.
RAY: If the door drains are clear and there’s no water in there, then you might check the sunroof’s channels.
TOM: All of mine are set to HBO.
RAY: The water channels in your roof are supposed to drain away the water that gets in through the edges of the sunroof’s opening.
