It has been the wettest spell of weather on record here. My car sits outside. I noticed the carpet was wet in the back and the front on the driver's side. Very wet!! It is coming in while the car is stationery, so not related to driving. The carpet up to the bottom of the doors is dry, so I suspect it is getting in the front. Drain holes are not visibly blocked.

Any ideas or previous experience out there?

Does your car have a sunroof?

No, it does not.
