Replacing Brake Lights on a 98

how the hell do I get to the bulb? The brake light lens doesnt seem to come off. Do I really have to peel back the interior carpet?
Also my car while being a very reliable daily driver over the last four years has developed a few hiccups.
Low Coolant light stays on even though the car is full of coolant.
Its going through a half pint of power steering fluid every six months but their are no apparent leaks????

I have a 97. Pull the trunk liner away from the tail lights. You'll see some nuts in there for the light assy. Remove the nuts, pull the assy off the car, the bulbs just pop in/out. Reverse for install.
