What must be disconnected before removing some panels?

• A. Electrical connectors or battery
• B. Windshield wipers
• C. Fuel injectors
• D. Door handles

Answer: (A)

Before removing panels, it’s essential to isolate the vehicle’s electrical system. Panels often hide wiring and connectors, and if power remains connected you risk short circuits, blown fuses, or even accidental airbag deployment while you’re prying and removing parts. Disconnecting the battery (usually the negative terminal) and/or unplugging electrical connectors removes energy from the circuits, making the work safer for you and protecting the vehicle’s electronics.

Other components like windshield wipers, fuel injectors, or door handles aren’t directly involved in the panel-removal process. They may be removed for access in some cases, but they don’t need to be disconnected just to take panels off, and doing so wouldn’t consistently prevent electrical hazards in the way disconnecting the electrical system does.

So the proper step is to disconnect the electrical connectors or the battery to ensure a safe, energy-free starting point for panel removal.
