Subaru A/C Compressor Failures (2014-2023): TSBs, Clutch Issues, and Replacement Costs

Symptoms of a Failing A/C Compressor

A bad A/C compressor will give you several warning signs. Ignoring them can sometimes lead to more expensive repairs if the compressor fails internally and sends debris throughout the A/C system.

• No Cold Air: This is the most obvious symptom. If the fan blows but the air is warm or only slightly cool, the compressor may not be engaging or pressurizing the refrigerant.
• Loud Noises: A grinding or high-pitched squealing sound when the A/C is turned on points to a failing bearing inside the compressor. A seized bearing can cause a loud squeal from the serpentine belt. Some owners report that these compressors can be noisy even when new, but a sudden change or a grinding noise is a clear sign of a problem.
• Visible Clutch Malfunction: The outer part of the compressor pulley is a clutch that engages to turn the compressor's internal components. You can observe this with the engine running and A/C on. If the clutch doesn't spin, is stuck, or wobbles, it has failed.
• Intermittent Cooling: The A/C might work fine when you first start driving but blow warm air when you're stopped in traffic or after the engine gets hot. This is often caused by the clutch air gap becoming too large, preventing the electromagnet from engaging the clutch when it's hot.
• Leaking Refrigerant: The compressor has seals that can fail over time, leading to leaks. You might see an oily residue on the body of the compressor. Low refrigerant levels from a leak will cause the system to stop cooling and can damage the compressor from running without enough lubrication.

Known Issues, TSBs, and Recalls

While there are no formal recalls for the A/C compressor on these vehicles, Subaru has issued several Technical Service Bulletins (TSBs) related to A/C compressor problems, particularly on earlier models.

TSB 10-84-16R: Faulty A/C Compressor Clutch

This is the most significant TSB for these vehicles. It addresses a known issue with the electrical windings inside the A/C compressor clutch assembly, which can cause the A/C system to stop working. This TSB applies to:

• 2014-2016 Subaru Forester
• 2014-2016 Subaru Impreza
• 2014-2016 Subaru XV Crosstrek

The bulletin advises technicians to replace the entire A/C compressor and clutch assembly with an updated part if a vehicle within a specific VIN range experiences this failure. While this was covered under the original warranty, some owners have reported receiving assistance from Subaru even after the warranty expired, so it's worth contacting a dealer if you have an affected vehicle.

TSB 15-209-17: Abnormal Sound from A/C Compressor

This bulletin also covers abnormal noises from the compressor and applies to several models, including the 2014-2016 Forester, 2012-2016 Impreza, and 2013-2016 Crosstrek. It acknowledges that some compressors may produce unusual sounds and may require replacement with an updated unit.

WRB-21 Service Program: A/C Condenser Corrosion

Though not a compressor issue, it's important to note that 2017-2018 Subaru Forester models were subject to a service program (similar to a recall) for A/C condensers that could corrode and leak refrigerant. A leak from the condenser will cause the A/C to stop working and could be misdiagnosed as a compressor problem. A dealer can check if this service has been performed on your vehicle.

Buying a Used A/C Compressor

A used OEM compressor can be a reliable and cost-effective alternative to an expensive new unit, especially when compared to cheap aftermarket options which may have quality and fitment issues. Here’s what to check before buying:

• Inspect the Clutch and Pulley: Spin the pulley by hand. It should rotate smoothly and quietly. A rough, grinding feel indicates a bad bearing. Try to wiggle the pulley; there should be no side-to-side play.
• Check the Clutch Face: Look for signs of extreme heat, like discoloration or a burnt smell. This indicates the clutch may have been slipping or has failed.
• Verify Part Numbers: Match the OEM part number from your old compressor to the used one. Part numbers for these vehicles include 73111FJ000, 73111FJ040, 73111FJ041, 73111FJ042, and 73111FL100/101. The numbers often supersede each other, so cross-referencing is key.
• Examine Electrical Connectors: Ensure the electrical connector on the compressor is intact, with no broken plastic or corroded pins.
• Look for Leaks: Check around the seals and case halves for oily residue, which is a sign of a refrigerant leak. The ports should be capped to prevent moisture and debris from entering.
• Ask About the Donor Vehicle: If possible, find out the mileage of the vehicle the compressor came from. Lower mileage is always better. Also, ask if the A/C was working when the part was removed.

Cost Breakdown

The cost to replace an A/C compressor can vary significantly based on the parts you choose and who performs the labor.

Replacement Difficulty & Procedure

Replacing the A/C compressor on these Subaru models is moderately difficult, primarily because it requires specialized equipment to handle the refrigerant.

• Difficulty Rating: 4 out of 5
• Estimated Time: 2-3 hours
• DIY Feasible: Not recommended for beginners.

The compressor is typically located on the top of the engine, making it relatively easy to access. However, the law requires the A/C system's refrigerant to be recovered by a licensed professional with an EPA-certified machine before any lines are disconnected. After the new compressor is installed, the system must be put under a deep vacuum to remove all air and moisture before being recharged with the precise amount of refrigerant and oil. While a mechanically inclined person can physically swap the compressor, the evacuation and recharge steps must be done by a professional shop.
