dog hair

I just got an '04 cav-i have gotten most of the dog hair out of the back seats,and behind them,but i can't get into where the rear window brake light is,looked underneath and can see where bulb is but how to get into it.the hair sure found its way into it,but how do i?it is the coupe and i can see the bulb from the trunk.

you have to take out the rear deck.

you have to take out the rear deck.thanks deadblade.i checked it out and it came out easier than i thought.folded back seats down and pulled out the two push clips(not sure what called)freed the deck right up.
