Car AirCon Compressor For Chevrolet Trailblazer 2.5 CSP17 2012-2017 WXCV068

The compressor is the power unit of the air-conditioning system that puts the refrigerant under high pressure before it pumps it into the condenser, where it changes from a gas to a liquid. A fully functioning compressor is necessary for the air-conditioning system to provide peak performance. On most cars, A/C compressors are driven by an engine-accessory belt. If the belt is worn and slips, the compressor won’t operate at full strength. Compressors can also leak refrigerant, resulting in less cold air going into the interior. Internal parts can also fail, leading to no cold air. Not all air-conditioning problems are because the system is low on refrigerant. Some are caused by issues with system parts, such as the compressor.

WNRLN Packing

ß ß ßWNRLN packaging and shock-proof foams, which have protective functions.

Their thickness is thicker than ordinary box and foam , Relatively speaking, the quality of WNRLN packaging is better than that of ordinary packaging.

ß ß ß It has the advantages of good stiffness and high wear resistance.

It is deeply loved by domestic and foreign customers.

Emergency situations

Some emergency indicators that something is wrong with your compressor include:

• Weird noises: This could be caused by a worn or broken belt/pulley. There are several other issues that may need to be addressed immediately.

• Burning smell: The compressor wiring may be damaged or burned.

• Leaking dashboard: It could be caused by a clogged hose or drain. Age and moisture can also cause your system to leak.

If you notice any of these issues, it's important to fix the problem as soon as possible.

General system

Each system may vary slightly per vehicle. For example, some may include an orifice tube whereas others have an expansion valve. This means the system has up to 7 components including:

• Compressor: compresses cool refrigerant gas into hot refrigerant gas

• Condenser and fan: converts hot refrigerant gas into a hot liquid at high pressur

• Receiver Dryer: temporarily stores refrigerant when not needed by the system

• Expansion (TX) Valve / Orifice Tube: regulates refrigerant flow / creates pressure drop

• Evaporator: cools air before entering cabin

• Heater Core: warms air before entering cabin (uses engine coolant rather than refrigerant)

• Blower Motor: fans hot or cold air into the cabin
