AC Wiring Diagram Components
The AC wiring diagram for a 2004 Chevy Silverado includes several components, such as:
- Compressor
- Condenser
- Evaporator
- Refrigerant lines
- Control module
Compressor
The compressor is the central component of the AC system. It compresses the refrigerant and sends it to the condenser to be cooled. The compressor is operated by the AC clutch.
Condenser
The condenser is located in front of the radiator and is responsible for cooling the refrigerant. It also converts the refrigerant from a gas to a liquid.
Evaporator
The evaporator is located inside the passenger compartment and is responsible for cooling the air. It removes the heat from the air as it passes through the system.
Refrigerant Lines
The refrigerant lines connect the different components of the AC system. The lines carry the refrigerant from the compressor to the condenser, to the evaporator, and back to the compressor.
Control Module
The control module is responsible for regulating the temperature and operation of the AC system. It receives input from the temperature sensor and the AC switch, and controls the operation of the compressor and other components.
