I took my car through a car wash in the morning and later that night I noticed there was water on my passenger floor board and up under my dash. I don't know if it is coming from my heater core or if it is just a clogged drain. Any input?
If your vehicle has a sunroof, often times the drains on the sunroof will leak. The drains are routed down the A pillars. Often times when they split or fall off the sunroof channels they will allow water to leak into the passanger compartment. Usually it winds up on the driver or passanger floor.
