HID Bulb Ballast
An HID Bulb Ballast limits the amount of current that flows in an electrical circuit. Aside from HID, metal halide and mercury vapor lights use ballasts to avoid a sudden rise in current.
A bulb ballast essentially regulates power and acts as an electrical resistor or reactance.
Ballasts can either be magnetic or electric.

HVAC Air Adjustment Control Motor
The HVAC Air Adjustment Control Motor is responsible for controlling air distribution in various A/C vents. It responds to the signal sent by the HVAC control unit. This motor is crucial to the operation of your HVAC system.

HVAC Air Inlet Door Actuator
An HVAC air inlet actuator is an electric motor inside a vehicle that helps provide air ventilation. It does so by controlling the temperature of the air flowing from the vents by mixing hot and cold air from the heater core and the evaporator.
There are two types of door actuators: the mode door actuator and the recirculation door actuator. The former controls vents that have airflow (floor, panel, or front, defrost), while the latter controls the intake of air into the system by bringing outside air or recirculating air inside.

HVAC Air Inlet Door Actuator Connector
The HVAC Air Inlet Door Actuator Connector is used to connect electrical components, such as the actuator and the harness terminals. The actuators themselves are motors that can move the inlet door back and forth, and the connectors are what allow these motors to move by drawing power from the terminals.

HVAC Air Inlet Housing
The HVAC air inlet housing is a component that’s responsible for leading air from the vehicle’s exterior to the evaporator where air is cooled. The air inlet is typically located below the windshield because this area allows the HVAC system to take in fresh air.

HVAC Air Inlet Position Sensor Connector
The HVAC air inlet position sensor connector is a component that attaches the sensor monitoring the HVAC air inlet to the cable leading to the vehicle’s powertrain control module (PCM). It enables the transmission of readings on whether the air inlet is open or closed and how wide the opening is, which the control module can use to adjust relevant processes.

HVAC Blower Motor Connector
The HVAC Blower Motor Connector is a set of wires that connects the HVAC blower motor to the blower motor resistors. The connector allows the resistors to control the blower motor’s speed depending on the number of resistors that are bypassed in the stepped resistor circuit. When no resistors are bypassed, they drop the maximum amount of voltage from the circuit, lowering the current that runs through the connector to the blower motor. This drop lowers the blower motor’s speed. The fewer resistors are bypassed, the higher the current, and the faster the blower motor runs. This is how climate control systems without automatic temperature controls adjust their fan speeds.
