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.

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.

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.

The Carquest condenser is an integral component of the motor vehicle air conditioning system. This part condenses the refrigerant into a liquid to prepare it for entry into the compressor. The condenser is manufactured according to OEM design specifications to ensure a long life with quality performance. Exact design standards produce a seamless fit into the engine compartment.

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. 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).

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.

ACDelco GM Original Equipment ABS Wheel Speed Sensors are located at each wheel, monitoring the rotation of each wheel, and are GM-recommended replacements for your vehicle’s original components. The sensor provides this speed information to the antilock brake control module for the antilock braking function. These sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

This direct replacement ABS wheel speed sensor matches the fit and function of an original equipment sensor. Made of quality materials with factory-style electrical connectors, this sensor has been designed and tested to be durable and reliable.

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).

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).

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.
