Where is the fuse for electric fan radiator on a 2006 Chevy Z71?

The fuse for the electric radiator fan on a 2006 Chevy Silverado Z71 (assuming you meant Silverado, as Z71 is a trim level, not a model) isn't a single, easily identifiable fuse like a headlight fuse. The system is more complex and often involves relays and may even have multiple fuses involved depending on whether the fan has multiple speeds or other integrated functions.

You won't find a fuse labeled "Electric Radiator Fan".

To find the relevant fuses and relays, you need to consult your owner's manual. This is the most reliable source. It will show you the location of the fuse box (usually under the hood and/or in the interior), a fuse diagram, and may specifically identify the relevant fuses and relays for the cooling fan system.

If you don't have your owner's manual, you can usually find a digital copy online by searching "[year] Chevy Silverado [engine size] owner's manual" (replacing the bracketed information with your vehicle's specifics). Alternatively, you can use a reliable online parts website (like AutoZone or Advance Auto Parts) and search for your vehicle's fuse box diagram.

Important Note: Before working on any electrical components, always disconnect the negative terminal of your battery to prevent electrical shock or short circuits.
