Rain water is leaking into interior from somewhere in the front passenger compartment. It is not a coolant leak, have checked and confirmed all water drains are not clogged (firewall drains, sunroof drains); tried using sprinkler to recreate leak but not successful. Water bleeds down the back of the front rubber kick pad which looks to run up to the top of the dash. Have not been able to identify root cause.

Appreciate advice on how best to identify and resolve this issue.

Hi and thanks for using 2CarPros. Com.

Water leaks are difficult to find. However, there are technical service bulletins related to leaks on this vehicle. I am going to attach all that are listed. There are three parts, A, B, and C.
This bulletin involves resealing: "A"- door seals/weatherstrips and/or water-shields, "B" windshield, and/or "C"- A-pillar to load beam to cowl body joints.

If you make it to C, you are not going to be happy. Lol
