Heating and Cooling System
* Heater core: The heater core is located behind the dashboard, on the passenger side of the vehicle. It is a small, metal radiator that is filled with hot water from the engine. As air flows through the heater core, it is heated and circulated throughout the vehicle.
* Blower motor: The blower motor is located on the passenger side of the vehicle, behind the glove box. It is responsible for circulating air through the heating and cooling system.
* A/C compressor: The A/C compressor is located on the front of the engine. It is responsible for compressing refrigerant gas and circulating it through the A/C system.
* A/C condenser: The A/C condenser is located in front of the radiator. It is responsible for dissipating heat from the refrigerant gas.
* A/C evaporator: The A/C evaporator is located behind the dashboard, on the passenger side of the vehicle. It is responsible for absorbing heat from the air and cooling it down.
Vacuum System
* Vacuum pump: The vacuum pump is located on the back of the engine. It is responsible for generating vacuum, which is used to operate the brakes and other vacuum-powered devices.
* Vacuum lines: The vacuum lines are hoses that connect the vacuum pump to the various vacuum-powered devices.
