The tail light don't get out
Inside the trunk under the carpeting you should find the connector connected to the light. Turn the connector and you should then be able to pull the light assembly out to access the bulb. Make sure to tighten the connector after replacing the bulb and putting the assembly back.
SOURCE: i need to know how to get the tail light lens cover off to change signal bulb
Open hatch and on inside of body where the lens is are two horizontal screws going into the lens, remove them and pull the lens towards the back of the vehicle carefully. Good luck
SOURCE: Need fuse schematic
if the fuse was blown the stop lights on both sides would be inop, also if the stop light circuit were dead u would be unable to get the trans out of park, use a 12 volt test light and test the brake light switch at the top of the brake pedal, u can buy a test light from Autozone, kragen and others for about $5 US. If the system has power cjheck the bulb socket it may be defective, use the 12 volt test light while someone pushes the brake pedal. let me know what u find and i will give u further assistance as ness.
SOURCE: Right brake light out; tail light works fine
most rear tail lights and turn/stop lights are the same dual filiment bulb. it is possible for your tail light to work and your brake light not to and still have a bad bulb. I would check the bulb first, your brake light works on the left yes? this would mean that the fuse is fine
SOURCE: Left Brake light out.
Check in fuse/relay box under hood on driver side for fuse blown. Map is on underside of cover.

Check for a bad socket assembly. Look for burnt retainers inside the socket.
