What fuse operates the ashtray light on a Buick Regal?

There isn't a single, universally applicable answer to which fuse controls the ashtray light in a Buick Regal. The specific fuse depends on the year and model of the Regal. The location of the fuse box also varies.

To find the correct fuse, you must consult your vehicle's owner's manual. The manual will have a fuse diagram showing which fuse controls which circuit, including the ashtray light (often labeled as "Ashtray," "Cigarette Lighter," or a similar description).
