Where is the rear defog switch on a 92 Buick Roadmaster?

The rear defogger switch on a 1992 Buick Roadmaster is typically located on the center console, near the climate control knobs. It's often a small, separate switch rather than being integrated into the climate control panel itself. However, it's possible (though less common) that it could be integrated into the climate control panel. Look carefully around that area for a small switch with a rear window graphic or the words "Rear Defogger."
