The latest vehicle models are equipped with an HVAC (Heating, Ventilation, and Air Conditioning) system. Its primary purpose is to regulate and maintain the interior air temperature based on fixed settings.

Air Ventilation, car interior parts

The air conditioning system of your car uses the air recirculation method to cool the air inside the car by recirculating it. Conversely, the fresh air method involves bringing atmospheric air inside the vehicle through an air duct located at the car’s front. Each mode has its own advantages and disadvantages.

3) Rear View Mirror

An interior component called the rear-view mirror enables the driver to observe the area behind the car by looking into the rear window, including the space occupied by passengers.

The door opening trim also referred to as window molding, is constructed of rubber or plastic. The trim is attached to the car body around the door area.

It serves multiple functions, including shock absorption, visual enhancement, and interior sealing. Additionally, it also assists in securing the window in place and provides protection to the window glasses.  

23) Turn Signal Indicator

A car is equipped with four turn signals positioned on all four sides of the vehicle. Inside the car, the turn signal indicator is typically represented by green arrows pointing in the desired direction.

Turn Signal Indicator

Some cars have turn signals integrated into the left side of the power steering system. The turn signal indicator operates by moving the lever upward to indicate a right turn and downward to indicate a left turn.
