Hello and welcome.
Is there also water on the floor in the rear compartment floor?
Yes, check that and let me know...
Yes, i did get that last info as i sent my response.
There is no recall on this problem.
There is however a service bulletin for the problem you have. This is your most likely problem.
There is a "Cowl Plenum drain" that has a fault where is does not allow water to drain quickly enough, and then enters the truck.
The cowl is the panel bewteen the hood and the windshield.
Under the hood, just below the rear hood seal, there is a rubber drain that needs to have 2 slits cut in it to allow to drain better. This drain is about in the center of the truck, on the firewall.
Here is a pic of what the drain looks like. Cut two 1 inch slits at the sides labled 1 and 2.
No sorry. These are copyrighted materials.
But I can give you the number to reference.
