2003 GMC C7500 Topkick Air Conditioning Parts

The condenser removes heat from the A/C refrigerant within the system. In late model vehicles, condensers cannot be cleaned or flushed. It is recommended to replace the condenser whenever a new compressor is installed for optimal performance.

Carquest A/C Accessories provide a comprehensive offering of premium quality fittings and tools to service all aspects of an a/c service from the most simple fitting replacement to complex diagnostics required for late model applications.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

Carquest Premium Vehicle Solutions provides high-quality solutions for a wide range of applications. The HVAC Pressure Sensor/Switch monitors the refrigerant pressure within the air conditioning system, ensuring optimal performance and preventing potential system damage, which enhances climate control and passenger comfort. Engineered for maximum performance and durability, our products are built to excel in even the most demanding conditions, ensuring reliable operation and long-lasting value.

GM Genuine Parts HVAC Pressure Switches are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These HVAC pressure switches are a system protective switch that cuts off power to A/C components if the pressure in the system is too low. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

High quality OE replacement part with all components needed to complete the job

Carquest Orifice Tubes are designed to regulate the flow of refrigerant through the air conditioning system to provide optimal cooling to the passenger compartment. Each orifice tube is manufactured to original equipment specifications to perform its function even in the harshest climates. Each part is supplied with the necessary gaskets and o-rings for installation.

GM Genuine Parts A/C Orifice Tubes are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These tubes, which separate the high and low pressure sides of the air conditioning system, control the flow of low pressure liquid refrigerant into the evaporator. The orifice tube is essentially a calibrated restriction located at the inlet to the evaporator. This causes the necessary pressure drop to allow the liquid refrigerant to evaporate within the evaporator and absorb heat. Since the orifice tube is fixed, the system is regulated by either cycling the compressor clutch or by a variable displacement compressor. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Protect your A/C system with our A/C Clutch Cycle Switch. Mounted on the low-pressure side, it continuously monitors refrigerant pressure to detect when levels drop below a safe threshold. In response, it automatically disengages the compressor clutch to prevent damage. Crafted from premium materials to withstand harsh conditions, this switch helps ensure reliable cooling performance and prolongs the life of your compressor.

GM Genuine Parts A/C Clutch Cycle Switches are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These A/C clutch cycle switches are component sensors that monitor the evaporator temperature and pressure. The switch turns the compressor clutch field coil off and on. When the pressure and temperature are too low, the compressor is switched off.

Carquest New Compressors are designed, manufactured and tested to meet or exceed strict original equipment specifications for superior quality and performance. Each new compressor is tested to provide durable life to the vehicle’s air conditioning system. All new compressor components are assembled using state of the art equipment and techniques to ensure smooth operation. Each part is equipped with a clutch and connector that matches the original equipment part and provides an exact replacement to your vehicle’s part. All compressors are supplied with the necessary gaskets and o-rings for installation.

Our compressors are built with high-quality components for superior reliability and performance. Engineered to reduce fuel consumption and minimize noise, they enhance driver and passenger comfort. Designed as direct replacements, they ensure a perfect fit and easy installation. Every compressor and component is brand new-never remanufactured-and undergoes rigorous multi-point quality testing to guarantee durability and performance. Trusted for industry-leading quality and reliability.

GM Genuine Parts A/C Service Valves are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These spring-loaded valves allow service access to the A/C system. The service valves allow the service technician to evacuate and recharge the refrigerant in the A/C system. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

The accumulator/receiver drier is designed to remove moisture from the A/C system. Every time the A/C system is opened, the accumulator/receiver drier must be replaced. Changing the accumulator/receiver drier is required when servicing the A/C system.

Carquest Accumulators and Receiver Driers are designed to store, filter and dry the air conditioning refrigerant to provide proper performance and durability for the air conditioning system. They are manufactured to meet or exceed original equipment specifications.

Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.

GM Genuine Parts A/C Refrigerant Line Seal Kits are designed, engineered, and tested to rigorous standards, and are backed by General Motors. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles.
