* Owner's Manual: The most reliable source is your vehicle's owner's manual. It should have a detailed fuse box diagram and descriptions of what each fuse protects.
* Inside the Fuse Box(es): There's usually a diagram either printed on the inside of the fuse box cover or on a sticker affixed nearby. Chevy trucks often have more than one fuse box (under the hood and sometimes inside the cabin).
* Online Repair Manuals: Websites like Chilton, Haynes, and AllData offer repair manuals that include detailed fuse box diagrams. These are subscription-based services, but offer much more comprehensive information than just fuse diagrams.
* Online Forums and Communities: Searching online forums dedicated to Chevy trucks (like the Chevrolet Truck Club forums) might reveal someone who has already posted a diagram or can point you to one. However, verify the accuracy of any information found this way.
* Your Local Mechanic or Auto Parts Store: A mechanic or a parts store employee might have access to a fuse box diagram or a readily available printed version.
Remember to always disconnect the negative battery terminal before working with any fuses or electrical components in your vehicle. This is a crucial safety precaution.
