Ever had water get in the rear window area??

We have unprecedented amounts of rain here in the last couple weeks. Record flooding. My truck sits most of the time. Here for the past couple of days I hear water sloshing when I make turns. It sounds like it’s coming from behind the rear seat.
I have pulled all 875 half empty water bottles the kids have left in the back and have a full tank of gas and it’s still there.
Today it’s actually been warm and dry. Both times I have rolled up the rear window it has had condensation on the inside of the glass.
I am presuming water has made it in the void there. Are there drain holes that are likely clogged?
Of course I have a bunch of stitches in my back and the moment and can’t remove the seats until after Wednesday when they come out.

I felt around under the seat it is not wet, I tried to look from above but can’t get the gap wide enough to see the bottom.
The top area above the seat and the white fabric backing is dry as a bone and not discolored.
The window has not been left down in the rain at all.

 

@Black similar issue with mine. I noticed when I went through a drive through car was I could hear the dryers blow air into my car. When id roll the rear window down id smell mildew in the cab. I replaced the rear window seals on the exterior and it fixed the issue. I feel like there should be some drain holes but I couldn't find any.

 

happen to have parts numbers how was the removal/install

 

I always wondered if our 3rd brake lights leak like the F-150 and allow water into the truck and rot the cab corners from the inside out.

 

I think with the design of our truck you would see staining to the headliner if it was leaking at the brake light.

So I pulled everything out and vacuumed (thanks kiddos for all your gifts)


Then I got the back panel off and sure enough it was full of water and what looks like mulch

As I cleaned it out more of the wet mulch seemed to come in from these little indentations along the back wall. I presume they are weep holes for water to drain between the cab and the bed. I haul a fair amount of mulch and that area between the cab and the bed is full of leaves and mulch so I am guessing the are all clogged. I need a long reach airwand to get between there and clear it out.

I wiped out all the wetness and ammo to let it air dry for a few hours. Then I am going to spray that whole area with Eezox to keep the moisture out and keep any of that from rusting. No signs of any corrosion yet thankfully.

 

I would have to dig them up again its been about a year. I do remember there was an interior trim piece vs an exterior. Exterior was the only one I replaced. Super easy install. 10 min job.

 

I need to go and do this. Honestly didnt even know it was an accessible area.
