What system includes power windows and locks?

• A. The body electrical system
• B. The engine management system
• C. The climate control system
• D. The braking system

Answer: (A)

Power windows and door locks are operated by the vehicle’s body electrical system. This system handles the 12-volt circuits that power electrical accessories, including window motors, door lock actuators, switches, fuses, and wiring harnesses. It’s separate from the engine’s electronics and from other subsystems like climate control or braking, which manage engine performance, HVAC functions, and braking safety, respectively. When diagnosing issues with windows or locks, you’d look at the body electrical wiring, fuses, relays, and possibly the body control module that may govern these accessories.
