Wow , For all those who haven't changed theirs
mine WAS FULL of ground up leaves and dirt.
2005 roadster here.

Take the cowl off and look for more leaves there as they can block the drains under the windshield and flood the car inside.
If you do not want to take the cowl off you can use a flashlight and peer under the rubber toothed barriers at each end of the cowl.

 

Thank You.
I will have to go out and check that as well.
No dont need a flood inside.
Thanks For the great advice!
