It's been raining quite a bit lately in Oregon and I started getting a water leak on on the inside of my car in the passenger footwell. Carpet was soaked from front to back. After drying and ruling out the easy possibilites first (sunroof drains, seals ect...) I hosed my car off with a lot of water and checked. Noticed water leaking down from next to my footwell vent as the source of the leak. Checked the cowl drain that is on the firewall, it felt very squishy. Squish it the other way to open it up and bingo, down drops a lot of water and a lot of crap. It was so plugged up with sludge that all the water in my cowl was coming inside. Just thought I'd throw it out there to you guys who might have a similar situation. It's an easy check, so give it a shot.
