Question moved to correct category.

Try cleaning throttle body and MAF, but you probably need a good local auto electrician with a pro grade scan tool computer.

If the rear light on the other side goes on and off by pushing on the light then i would say the switch in the one that stays lit it either stuck or broken and may need to be replaced. i think you could stop by a body shop and they would be able to do it for less money that a Buick dealer would.

Why is the question

Do you have a blown fuse?

Replacing a blown fuse is not
a fix for anything,they blow for a
reason

Sit in back seat passenger side. Remove panel which is on top which is below rear window, same panel where seat belt goes into panel at top. You will need to remove #2 Phillips screws which hold panel in place. Screws are hiding behind seat belt front cover where belt goes down in panel, under cup holder which allows arm rest cover to lift off and one more right on left side of head rest in corner. Remove panel. You will see switch which is in vertical position. If for any reason you want to by-pass switch, just unplug switch. Radio will still work in standard mode. The amp sound will not increase in performance when top is down and sound will not be as sharp.

There is no fuse marked for dome light's in the rear fuse box. The BCM - body control module controls the dome / courtesy light's .
The body control module (BCM) monitors the courtesy lamp switch signal circuit in order to determine when the courtesy/dome lamps should be illuminated. When the BCM senses that the courtesy lamp switch signal circuit is grounded when the switch is activated, the BCM will directly illuminate the courtesy/dome lamps.

You should possibly think about taking your vehicle to a qualified repair shop !
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, observe the courtesy lamp switch parameter in the body control module (BCM) data list.

maybe a relay?check under hood and in cab!!!Good Luck!!!

check for voltage at the lamps themselves. If no voltage is present, check headlamp relay,.Rarely it could also be the multi-function switch, but don't go there first! Also, did you try a new bulb?(s)
