To find it, you'll need to:
1. Consult your owner's manual: This is the most reliable source. The manual will have a fuse box diagram showing the location of all fuses and what each one controls.
2. Check the underhood fuse box: Most Suburbans have a fuse box under the hood. It's usually located near the battery.
3. Check the interior fuse box: Some Suburbans may have the hood light fuse in the interior fuse box, often located under the dashboard.
4. Look for a fuse labeled "Hood Lamp," "Dome Lamp" (sometimes the hood light shares a circuit), or "Exterior Lamps." The label might not be perfectly descriptive; you might have to experiment if you can't find one clearly labeled.
Without knowing the year and model of your Suburban, it's impossible to give a more precise location. Always refer to your owner's manual first.
