No, the 2001 Chevy Blazer doesn't have a single, universally located "access panel" like some vehicles might have for specific components. Access to various parts and systems is achieved through different panels, doors, and hatches depending on what you need to reach. For example, you'd access the battery through the engine bay, fuses might be under the dash or in the engine compartment, etc.
To access something specific, you'll need to consult your owner's manual or an online repair manual to determine the correct access points.
