A/C Not Cooling in my 2017 Acura ILX - Compressor issue?

Vehicle: 2017 Acura ILX Premium

Hey everyone,

My 2017 Acura ILX Premium, with about 60,000 miles, has developed an issue with the air conditioning. It's blowing warm air, even on the coldest setting. I had a local shop check the refrigerant, and they said it was fully charged, so it doesn't seem to be a leak.

I've heard that A/C compressor failures can be a thing with some Honda/Acura models around this age. Could this be what's happening with my ILX? I don't hear any strange noises when I turn the A/C on, but it just doesn't cool.

Any thoughts or similar experiences with a 2017 ILX A/C? What should I be looking for?

ClearTheCode admin answer:

Warm air from your 2017 Acura ILX's A/C, despite a full refrigerant charge, strongly suggests a component failure within the system. A common culprit for Honda/Acura vehicles of this era is indeed the A/C compressor clutch or the compressor itself.

  1. A/C Compressor Clutch:
    • Function: The clutch engages the compressor when the A/C is turned on, allowing it to pump refrigerant. If the clutch fails to engage, the compressor won't spin, and no cooling will occur.
    • Check: With the engine running and A/C on max cold, look at the front of the A/C compressor. The outer plate should be spinning with the pulley. If the pulley spins but the outer plate doesn't, the clutch isn't engaging.
  2. A/C Compressor Relay:
    • Function: This small relay in the fuse box sends power to the compressor clutch. A faulty relay can prevent the clutch from engaging.
    • Check: You can try swapping the A/C compressor relay with another identical relay from a non-critical system (like the horn relay) in the fuse box to see if the A/C starts working.
  3. Causes:
    • Electrical Failure: Faulty relay, wiring issue, or a bad pressure switch.
    • Mechanical Failure: Worn-out compressor clutch or internal compressor failure.
  4. When to See a Shop:
    • Soon: If the relay swap doesn't work and the compressor clutch isn't engaging, or if you suspect an internal compressor issue. A professional can diagnose the exact point of failure.
    • Diagnostics: A technician will check for power at the compressor, test the pressure switches, and look for any relevant OBD-II codes (e.g., P0530 - A/C Refrigerant Pressure Sensor Circuit Malfunction). If the compressor is confirmed faulty, replacement is typically required.
