Mysertious water puddle in rear passenger area after rain.

[PerryD]

Hi everyone new to the forum. I was wondering if anyone has any insite on this leak in my car. After rain a puddle forms in the rear right passenger foot area. if it is heavy rain over night it can about be a half inch of water standing! My car does have a sunroof but it is never used and is completely dry around every part of it. All the weather stripping is also intact and all the interior besides this part of the floor is also dry. Anyone had a similar problem they fixed or solutions to try? thank you.

car is 2002

You're going to need to pull up the carpet and let it dry properly otherwise you're just asking for mold/mildew problems in a few weeks. It's not a hard job, if you need help or want pointers feel free to ask.

CheeseHelmet posted the good info. I would bet its the cowl drain, and it fills up and then floods into the passenger side through the blower. Pull the skirt from the front passenger wheel well and blow out the drain with some compressed air and poke a long skinny screw driver in there.
