2021 GMC Terrain Air Conditioning Parts

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.

This A/C service valve cap is designed to match the fit and function of the original cap on specified applications, and is engineered for reliable performance and durability.

Carquest Premium anti-lock brake system (ABS) wheel speed sensors are designed to perform in harsh environments and meet or exceed original equipment (O.E.) specifications. Carquest Premium ABS sensors are built by manufacturers that meet IATF 16949 certified framework, an internationally recognized proof of quality in the automotive industry. Each ABS sensor undergoes extensive validation testing to ensure long-lasting performance and reliability. Carquest Premium ABS sensors are part of our Carquest Vehicle Solutions, which is a full line of engine management and electronics products that help control ignition, fuel delivery and emission systems. Carquest Vehicle Solutions are OE-quality parts designed, engineered and tested by world-class manufacturers to ensure a reliable and long-lasting repair.

The Accelerator Pedal Position (APP) sensor provides a signal identifying the location of the accelerator pedal to the engine control module. As the vehicle operator requests various degrees of torque from the engine the signal from the sensor provides the engine computer the necessary information to implement the request. The sensor provides two positive slope signals that have an offset voltage range and increase at different rates, the two signals from the sensor provide the engine computer with two unique signal inputs ensuring safety should one signal fail.

The ABS or Anti-Lock Brake System ECU monitors the Wheel Speed Sensors rotational speed for anti-lock brake function, stability control and traction control. The ABS sensors report the speed of all four wheels to the ECU to determine if the wheels are locking up and to help provide safer stopping. Reasons for replacement include: ABS/brake lamp illumination, no or erratic ABS operation or problems with stability and or traction control systems.

GM Genuine Parts A/C Compressors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These compressors pump refrigerant through the system. The compressor is typically engine driven via the accessory belt, and a clutch on the compressor is used to engage and disengage the compressor. Hybrid vehicles are typically equipped with an electric motor driven compressor. The compressor is lubricated by refrigerant oil. 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.

Manufactured Compressors are built in a ISO9001:2015 Certified facility to ensure consistent quality standards in the manufacturing process.

The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Sensor reports system pressures to the on-board computer, in turn allowing the computer to properly and efficiently control the compressor, fans and system levels. An improperly functioning A/C Pressure Sensor will provide erratic or inaccurate readings to on-board computers severely affecting system performance and function. Without reliable and accurate data from a properly functioning A/C Pressure Sensor, on-board computers are unable to protect the safety of critical components and the system as a whole which can lead to excessive wear and tear on critical components and costly system damage.

ACDelco GM Original Equipment Multi Purpose Sensor is a GM-recommended replacement component for one or more of the following vehicle systems: hvac. This original equipment sensor will provide the same performance, durability, and service life you expect from General Motors.
