It has been raining steadily since I returned home and I have had to leave the 940 outside. I took out the passenger's mat to clean it and found the carpet beneath it to be sopping wet. This is not the first time this has happened. I usually keep the car in the garage however and it is not then a problem.

What are the most likely culprits? I took out some of the lower plastic molding along the right hand side of the car but this didn't reveal much to me. I suspect there is some kind of leak from the front cowl vent. I will try dousing the cowl with a bucket of water but if there is something that is a more likely suspect I'd appreciate your input.
