Answer 1

Option C

Both technicians are correct

Step-by-step explanation:

HVAC persists for Heating Ventilation and Air Conditioning. Its design in a vehicle is to cleanse, cool, flame, control, and dehumidify the air accessing the cabin, depending on the inputs of the operator as thoroughly as electronic sensors. Various systems will practice diverse ways of regulating airflow into the cabin but all act on identical basic principles.

The automatic systems are electric systems that want different inputs from sensors that intimate climate circumstances to obtain the aspired temperature. Vacuum actuators and/or electric motors control the air doors/valves in these systems.
