PXC14 A/C Compressor for the 2016–2018 Chevrolet Cruze: What You're Ordering

If the A/C on your 2016–2018 Chevrolet Cruze has quit, the part to order is the A/C Compressor w/ PXC14 Compressor for Chevrolet Cruze 2016–2018 (OEM 39067789). It is a Delphi/Hanon Systems variable-displacement scroll compressor that ships fully assembled, with the electronic control valve (ECV) and the 4.375 in. OD pulley already mounted.

As of May 2026, this unit remains the preferred service replacement across GM's global aftermarket network. It meets SAE J639:2024 safety standards and ISO 13043 refrigerant compatibility requirements, and it runs with GM's updated HVAC module firmware per TSB #22-NA-045. Cross-reference numbers on the same hardware: 39067803, 13346491, 13346495, 1522226 and Delphi PN TSP0155993.

Does it fit your Cruze?

• Fits: 2016–2018 Chevrolet Cruze (Gen II), Eco, LT and LTZ trims, 1.4L Turbo LE2 engine, VIN M.
• Does not fit: the diesel variants with LUZ or LNP engine codes.
• Clutch: included, pre-gapped to 0.45 mm with a shim kit for fine adjustment.
• Refrigerant: R-134a factory fill at 480g ±15g; R-1234yf retrofit supported after an ISO 46 POE oil flush.

The same unit also sits on two sibling catalog pages, listing 39067789 and listing 39067790, so you can compare stock and shipping before you commit. The AC & Heating collection at Koeep covers the rest of the climate system for cars and motorcycles.

2026 Material and Engineering Updates on the PXC14

Scroll metallurgy

The fixed and orbiting scrolls are now cut from hypereutectic Al-Si alloy (AL-18Si) instead of the older AL-12Si formulation. Thermal expansion mismatch drops by about 18% at high load, which means compressor speeds above 6,000 rpm. That targets the premature scroll wear documented in NHTSA TSB #PIP5540B for 2016–2018 Cruze builds.

Surface hardness is HRB 92 or higher, which also helps with R-1234yf and its slightly higher discharge temperatures.

ECV solenoid and PWM control

The electronic control valve runs a 400 Hz PWM base frequency with a ±2% duty-cycle tolerance per ISO 13043:2025 Annex C. Displacement modulation covers the full 2% to 100% stroke range. The valve is backward-compatible with GM's GMLAN HVAC bus and forward-compatible with CAN FD at 5 Mbps as that protocol rolls out across 2026 GM platforms.

Shaft seal and main bearing

A triple-lip PTFE/HNBR composite shaft seal replaces the older double-lip design and cuts refrigerant permeation by up to 40% over a 100,000-mile service interval. The main drive bearing is now an NSK 35BD5220 double-row angular contact ball bearing packed with Kluber Isoflex NBU 15 grease for better heat dissipation at sustained highway speed.

Every value below comes from the published data for this unit. Use it as your pre-order checklist and post-install verification sheet.

Diagnostics: Failure Symptoms and DTC Mapping

Warm air at idle, cold air on the highway

Classic PXC14 variable-displacement failure: at idle, roughly 650–750 rpm, the scroll needs enough ECV PWM duty cycle to hold displacement, and a solenoid outside the 10.5–12.8 Ω window cannot deliver it.

Check the A/C refrigerant pressure sensor (PID: AC_REF_PRESS) first: at 22°C ambient, static pressure should read 70–95 psi. If the sensor is valid but cooling still fades, measure ECV solenoid resistance at the compressor harness connector. Out of spec means replace the assembly; the PXC14 (39067789) from Koeep arrives pre-calibrated for plug-and-play installation.

Reading DTC B393B

B393B flags excessive current draw on the compressor ECV circuit. Per GM's updated diagnostic flow in TSB #22-NA-045, work the causes in order. First, an ECV solenoid short-to-ground: resistance below 8 Ω means an internal short, and the compressor gets replaced. Second, harness chafing at the compressor connector or along the front engine harness near the radiator support. Third, an HVAC module internal fault; rule out the first two.

Codes to scan before you condemn the compressor

• P0530: A/C refrigerant pressure sensor A circuit. Verify the sensor first.
• P0531: sensor A range/performance. Check refrigerant charge.
• P0645: clutch relay control circuit. Wiring or relay fault.
• B393B: ECV current above threshold. High probability the compressor needs replacement.
• B393C: ECV current below threshold. Open circuit; check the harness first.
• P0400 to P0499: EGR flow codes. The 2026 GM calibration can disable the A/C compressor on these.
• U0155: lost communication with the instrument panel cluster; can interrupt HVAC bus signals.

Clutch will not engage: check the air gap

A loud click with no compressor spin points at the clutch air gap. Specification is 0.35–0.65 mm (0.014–0.026 in); friction wear pushes the gap past 0.75 mm over time, and then the coil cannot pull the clutch plate in. Measure with feeler gauges, engine off, and reshim or replace the clutch assembly above 0.65 mm. Do not tap the plate to close the gap: that damages the compressor nose bearing and can cause failure within 500 miles.

OEM Validation and Compliance

The assembly meets SAE J639:2024 safety requirements for mobile air conditioning: burst pressure validation of at least 8,700 kPa, refrigerant permeation limits and A2L refrigerant compatibility. The triple-lip PTFE/HNBR shaft seal meets the §5.2.4 permeation standards for both refrigerants.

With a proper flush and correct charge, Koeep validates this unit for 2026–2030 service, and the 2026 inventory carries the latest Delphi/Hanon batch with all TSB #22-NA-045 revisions.
