A vehicle equipped with heated and cooled seats is in the shop for service. What special service may be required for the seats?

The temperature of heated seats is regulated by ________.

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?

A defective APP sensor will cause ________.

Which of the following actions will deactivate cruise control operation?

In an electronically controlled cruise control system, what component is used to monitor vehicle speed?

An open wire at point "A" would have what result?

Technician A says that many power windows and power door locks use a reversible, permanent-magnet motor with a built-in circuit breaker. Technician B says that the control switches and relays direct the current through the motor(s). Who is right?

Technician A says that a rear-window defogger can self-regulate the current flow. Technician B says that as the temperature of the grid decreases, its resistance decreases, reducing current flow. Who is right?
