Power windows are being discussed. Technician A says that when one control wire is disconnected all the power windows will fail to operate. Technician B says that a defective ground connection at the master control switch could cause the failure of all power windows. Who is right?

Question

Quizplus · Accepted Answer

Technician B is correct because the master control switch is often the central point for grounding the power window system in a vehicle. If there's a defective ground connection at this switch, it could indeed cause all the power windows to fail, as they might not receive the necessary electrical circuit completion to operate. Technician A's statement is generally incorrect because disconnecting one control wire, depending on the system's design, does not necessarily lead to all windows failing to operate; power windows often have separate circuits and controls.
