I have noticed lately when it rains a lot or when going through water, my passenger floor board is wet. It only the bottom part where it's flat not up the sides. And the channel for the wires at the door holds water. I checked condensation tube for a.c. and it is clear.

 

I've heard the 3rd brake light is a common source for leaks

 

All dry except for the front passenger floor,its either the ac draining on the floor or its coming from the grommet for the wires.

 

I've found my driver's side floor wet a few times this summer also. I can't tell where it's coming from.

 

Found the leak, thought it was around the drain. It happened to be the mounting stud beside it.
