How to access 3rd brake light- gen 3

Hello everyone,

like many others I’m dealing with the gasket behind my third brake light failing and now allowing moisture and water into the cab when it rains. I’ve tried searching both these forums and Google in general for a “how to” on accessing and replacing the 3rd brake light but have not been able to find much for gen 3.plenty of posts mention that you have to drop the headliner, or at least the back of it, but none really tell you how to do that. If someone has done this and can give a step-by-step on how to get the back of the headliner down to reach the light you’d be helping a lot of us out!

 

Here's some info, doesn't seem to be any videos of the process, others here may find one.

This is a problem only with the Double Cab. The Access Cab has screws on the outside of the light housing.
