Does anyone else's Mustang leak into the passenger side after getting washed or after it rains?

It's a pain to wash the car and then my Dad drives the car and my shoes get wet.

 

What model year? The S197 (2005-14) has an issue with a drain plug in the cowl getting plugged up. There are threads about it and how to fix it.

 

She's a 2008 base model, so you might have just figured it out for me. Thanks a bunch!

 

I thought I was alone. S197 07 here, and the backseat gets a puddle every now and then. Does your backseat floor get a puddle? I'm thinking the black rubber thing that aligns with driver side door's window is broken
