A Guide to the 2016-2021 Ford Expedition A/C Compressor
If your Ford Expedition's A/C is blowing warm, your compressor might be the problem; here's what you need to know.
- A/C system issues on 2018-2021 Expeditions are common, with forum members frequently reporting leaks from the evaporator core and compressor.
- When replacing the compressor, you must also replace the accumulator/drier and expansion valve/orifice tube to prevent immediate failure of the new part.
- Motorcraft is the OEM brand offering guaranteed fit, while Four Seasons is a reputable aftermarket alternative that provides good value.
- This is not a simple DIY job; it requires specialized equipment to safely handle refrigerant and properly service the system.
Is Your Expedition's A/C Failing? Common Symptoms
When an A/C compressor starts to fail, it usually provides a few warning signs. Ignoring them can lead to more expensive repairs down the road. Here’s what to watch for:
🎬 Watch this video to see common symptoms of compressor failure.- Warm Air from Vents: The most obvious sign is when the A/C system stops blowing cold air. If the fan works but the air isn't cool, the compressor may not be engaging or pressurizing the refrigerant.
- Strange Noises: A grinding or squealing sound when you turn on the A/C can point to a failing bearing inside the compressor or a problem with the clutch.
- Visible Leaks: The compressor has seals that can wear out and leak refrigerant oil. You might see a greasy residue on the compressor body or notice a hissing sound.
- Intermittent Cooling: In some cases, the A/C might work sometimes and not others. This can be a sign of the compressor clutch overheating or an internal issue.
Known Issues for 2016-2021 Ford Expeditions
While there are no direct recalls for the A/C compressor itself, some related issues are worth noting. Ford issued a recall for the A/C blower motor in 2015-2017 models, which could fail and pose a fire risk. Additionally, a Technical Service Bulletin (TSB 22-2089 🎬 Learn why your airflow might suddenly stop due to TSB 22-2089.) was released for 2018-2022 Expeditions concerning the evaporator temperature sensor, which can cause the system to freeze up and stop airflow. Another customer satisfaction program (20N08) was issued for certain 2018 Expeditions due to potentially contaminated refrigerant from the factory, which required compressor replacement. Owners in forums frequently report A/C leaks, particularly from the evaporator core, which can mimic compressor failure symptoms.
Choosing the Right Aftermarket A/C Compressor
When your compressor fails, you have a choice between OEM (Motorcraft) and aftermarket brands. For the 2016-2021 Expedition, both are viable options with different trade-offs.
- Motorcraft: This is Ford's official parts brand and the original equipment manufacturer (OEM). It guarantees a perfect fit and original performance. However, it is the most expensive option.
- Four Seasons: A very popular and long-standing aftermarket brand. It's generally considered a reputable choice that offers a good balance of quality and price. Some mechanics note that in certain cases, the Four Seasons part can be identical to the Motorcraft part, just with a different sticker.
- Global Parts Distributors (GPD): Another major aftermarket supplier offering new and remanufactured compressors. GPD is known for its wide range of A/C components and is a common choice for repair shops. User reviews are sometimes mixed, suggesting it's a budget-friendly alternative. 🎬 See a detailed Q&A about GPD aftermarket A/C compressors.
Pro Tip: Always Replace System Components
When a compressor fails catastrophically, it can send metal debris throughout the entire A/C system. This is often called "black death." To prevent your new compressor from failing immediately, you must also replace the A/C accumulator (or receiver/drier) and the expansion valve (or orifice tube). Flushing the system to remove any remaining debris is also a critical step. Many aftermarket brands offer kits that include these necessary components.
Cost of Replacing a Ford Expedition A/C Compressor
| Part / Service | Estimated Cost |
|---|---|
| New OEM (Motorcraft) Compressor | $600 - $930 |
| New Aftermarket Compressor (Four Seasons, GPD) | $305 - $630 |
| Shop Labor | $210 - $532 |
| Total Professional Replacement | $932 - $1,877 |
Costs are estimates and can vary based on your location, vehicle year, and the specific parts chosen. Total replacement cost includes the part, labor, and system evacuation/recharge.
Frequently Asked Questions
Can I replace the A/C compressor myself?
This is an advanced DIY job. While physically swapping the compressor is possible for a skilled mechanic, the A/C system requires specialized tools. You need a machine to safely recover the old refrigerant, a vacuum pump to remove moisture from the system after installation, and manifold gauges to recharge it with the correct amount of new refrigerant. For most owners, professional installation is recommended.
Why do some 2018+ Expeditions use a different, more expensive refrigerant?
Starting around 2018, many vehicles, including the Expedition, switched from R-134a refrigerant to R-1234yf. This newer refrigerant is more environmentally friendly but is also more expensive and requires different service equipment. Be sure to verify which refrigerant your specific vehicle uses before purchasing parts or attempting service.
Is a remanufactured compressor a good option?
Remanufactured compressors can save money, but their quality can be inconsistent. A remanufactured part is an old unit that has been rebuilt with new seals and bearings. For a critical component like a compressor, a new aftermarket part is often a more reliable choice for a small increase in price.
My A/C blows cold on the highway but not at idle. Is that the compressor?
This can be a symptom of several issues. It could be a sign of a slightly low refrigerant charge, which is often the first thing to check. It could also be an issue with the engine's cooling fans not pulling enough air across the condenser at low speeds. While it can be related to a weak compressor, you should check the refrigerant level and fan operation first.
