Center High-Mounted Stop Lamp (CHMSL)
This light is an LED assembly. See your authorized stealership

I presume you are talking about the centre one as the side are easy. I have changed them before but they are not easy lots of rewiring and time. You really have to replace the whole unit. Goodluck

LED lights have much lower resistance and draw, so the computer thinks the bulbs are blown even though they're working.
The only way to prevent the computer from doing that is to install a regular light bulb on each side in addition to the LED lights.

Put the old pad across the front of the piston and set a C clamp over it to the back of the piston housing. tighten the clamp and the piston will go in.

IT'S A BIT MORE COMPLICATED THAN ABOVE.
TO REMOVE BRAKE LIGHT HOUSING YOU HAVE TO GO INTO THE TRUNK AND REMOVE AN OVAL PLASTIC COVER NEAR WHERE THE TAIL LIGHT IS. REACH IN AND FEEL FOR A KNOB (FEELS LIKE AN OUTDOOR SPIGOT KNOB). TURN IT UNTIL IT COMES OFF. REMOVE ENTIRE TAIL LIGHT CASING. YOU'LL BE ABLE TO COMPLETELY REMOVE THE HOUSING BY PUSHING FROM INSIDE OUT. DISCONNECT THE WIRE. CHANGE BULB, REVERSE PROCEDURE.
GOOD LUCK.
