3rd Brakelight Cover Question

You mean the one behind your rear window?
Just pull up and towards your self, it should come off. It's not that hard, it just held by few clips or something. Try to play around with it if that won't work.
It's been a long time, I don't remember for sure.

ya, just pull up and towards you..it comes off very easily...and to put it back on just push towards the rear view and down and it should snap in

You could also refer to your owners manual, i think it tells you how with some diagrams.

just yank if off...and when your done put it back in with a good swift hit

if its like the gen 4, u can go at it from under neath in the trunk and push up the lil clips

Get a screw driver, pry it under, pop it up as best you can. Then pretty much grab and pull. Don't worry about breaking it, you won't. It just takes so force from the angle you have. (That's also the only way to get to the speakers)
