1998 Sedan base model. My passenger side front and rear floor stay wet during rain. I've checked everywhere for leaks. Pulled back the carpet and hosed the car down. No leak. I think it may be from the cowl or heat/AC air box drain. Where are those drains located? Pics would be helpful. Searching turned up nothing on the forum or internet.
