Shopping this compressor hands you a wall of numbers: 39067789 on one listing, 39067803 on another, 39038560 on your old case.

The part is the PXC14 A/C compressor for the 2016-2018 Chevrolet Cruze, reference 39067789. Every wrong purchase here starts with a number read out of context.

Three numbers that are one compressor

Order 39067789 for a 2016-2018 Cruze 1.4L gas car and you have the right part:

• 39067789 — the GM service reference a parts counter calls up.
• 13427936 — the earlier production reference for the same unit, superseded.
• 39176468 — the current GM kit with seals, oil separator integral. Its catalog page says it replaces both.
• Aftermarket: ACDelco 15-22365, Four Seasons 67570/68570, Ranshu 14-1418C — all the same unit.

All of them describe one fitment; the choice is packaging and warranty. Our complete guide to the 39067789 compressor covers the catalog history in depth.

39067803 is not a variant

Run 39067803 through the GM catalogs and nothing comes back. Only retailer pages carry it.

This store's import created sibling handles whose suffixes climb from 39067789 to 39067803; all titles read 39067789. The same PXC14 unit also sits on a handle ending in 39067800, with an identical title and price band.

• The suffix is a filing artifact, not an engineering revision.
• A number found nowhere except a seller's own pages is not a part number.
• Resolve the purchase by VIN and the under-hood label instead.

Every number on one table

P0530 through P0533: one sensor, four verdicts

These codes usually convict the sensor circuit, not the compressor. Test the cheap part first.

The sensor is the three-wire pressure sensor on the high side of the A/C circuit. The ECM — the car's computer — uses that reading to run the compressor and the fans.

• P0530 — the ECM saw a signal it cannot trust.
• P0531 — plausible electrically, wrong against running conditions.
• P0532 — the signal sits at the bottom of its range.
• P0533 — the signal sits at the top of its range.
• P0534 — the system lost refrigerant charge. That is a leak verdict, not a compressor one.

Now the twist behind most false verdicts. A stored P0530-family code typically makes the ECM refuse to engage the compressor, so warm vents do not prove a dead unit.

The compressor can still be guilty. A worn unit reads low on a full system; an overcharge or a blocked condenser reads high.

The five-step check that cannot misfire

Work in this order. Only the last two steps touch hardware.

1. Pull the full code set with freeze frame, and note whether the P053x codes are stored or pending.
2. Test the sensor circuit at the connector: reference voltage, ground, signal. An electrical fault ends the job at the harness.
3. Verify the charge against the label, then command the compressor on. No high-side rise on a full system is the compressor verdict.
4. Match the physical set: 110 mm pulley, five ribs, port orientation, clutch coil.
5. Confirm the refrigerant family from the label before you connect anything.

Do not skip the refrigerant label

Step five is not a formality. Production spans the R-134a to R-1234yf changeover, and the two refrigerants need different couplers and charge weights.

One 2017 Cruze built in April 2017 already wears an R-1234yf label. Reported charges run near 20 ounces on the earlier generation and near 17 on this one.

• Read your under-hood label before you buy refrigerant or hook up equipment.
• A partial can poured in by guesswork is not a service charge.

Our buyers guide to compressor diagnostics and refrigerant standards treats the label as the first checkpoint.

The generational trap: 3913319 is a different car

This mismatch costs the most time. Both generations are a Cruze with a 1.4L.

The 2012-2015 Cruze, and the 2016 Cruze Limited, take the 3913319 compressor with clutch for the 2012-2015 Cruze 1.4L. Mounting, ports and pulley all differ from the PXC14 unit.

• A 2016 Cruze = second-generation car, PXC14 application, 39067789.
• A 2016 Cruze Limited = first-generation body, 3913319 family.
• Same model year, same engine size, different compressor — pin the car down by VIN first.

Both applications sit in the A/C and heating collection.

Why the dealer kit costs four times as much

A GM dealer lists the 39176468 kit with seals at roughly $598. The standalone unit here lists at $180.96, and the previous-generation unit at $160.49.

The premium buys kit packaging, seals supplied together, and a dealer-backed warranty chain. At this age the economics favor the standalone unit.

The price must never change the reconciliation. A cheaper unit that resolves to 39067789 is correct; an expensive one ordered off a URL suffix is still a guess.
