How to fix the Leaking Rear Glass - Leaky Slider - Water Leak - Back Glass

Would this procedure also apply to the 2004-2008 F-150? I have a leak that I assume is coming from the back window in my 04.

Note that what may appear to be a leaky rear glass problem could be in fact a leaky 3rd brake light. A 10 minute job with some silicone might be your answer...

The reason I say it's the back glass is because whenever we get a heavy rain, the headliner is never wet. The water collects right next to the rear seat brackets that connect to the floor onboth sides of the cab.

My headliner never got wet either, water would run down the inside of the window and collect on top of the lower seal.

I am in the middle of following the steps... (which are great) .
I would just add you will need a Torx-50 head to remove the seat belts.

I did have a question though - beside the butle tape, there is a rubber weather stripping ? around the plastic frame.

Is that needed, mine is beat up and I was thinking I should fix? replace it ? What is it called and where can I get it.. Does it do anything? Do I need it? How does it stay in place?

Thanks for any advice.
