Here's what you might be looking for:
* Rear Window Defroster: This is the most common function related to "defog" in a vehicle. Check your fuse box for a fuse labeled "rear window defroster," "rear defroster," or "rear window heater."
* Other Electrical Components: Some vehicles have other components that are related to rear window defogging, like a rear window defogger relay or a rear window defogger timer.
* Fuse Box Diagram: The most reliable way to find the correct fuse is to consult the fuse box diagram in your 1997 Chevy truck's owner's manual. This diagram will show you the location and function of each fuse.
Important: If you're unsure about working on your vehicle's electrical system, it's best to consult a qualified mechanic.
