To find it:
1. Open the underhood fuse box: Locate the fuse box under the hood of your Alero (usually near the battery). The lid should have a diagram showing the fuse layout and what each fuse controls.
2. Consult the diagram: The diagram should clearly show which fuse is for the power outlet (often labeled as "Power Outlet," "Accessory," "Cigarette Lighter," or something similar). Look for a fuse with an amperage rating of around 15A or 20A.
3. Check the fuse: Visually inspect the fuse. If the fuse is blown, the metal filament inside will be broken or melted.
If you can't locate it using the diagram, your owner's manual will also have a fuse box diagram. If you don't have the owner's manual, you can often find a digital version online through a site like the Oldsmobile owner's site (if still available) or a general automotive repair manual site.
