Mitsubishi ASX: Cabin Air Filter Replacement

On the ASX, the cabin air filter is located behind the glove box. Replace it every 15,000-20,000 km (9,000-12,000 mi) or whenever climate control performance drops. The procedure is simple and requires no tools.

Difficulty: Easy Time: 10-15 minutes Steps: 10 Tools: None required (in rare cases, a flat-blade screwdriver)

Part

  • 🔩 Mitsubishi 7803A004 (standard) or 7803A005 (charcoal). Aftermarket equivalents: Mann CU22011, Nevsky NF-6199, Sakura CA-18360

Step by step

10 steps
  1. Open the glove box and take out its contents.
  2. Press the left side wall of the glove box inward (flexing the plastic) and pull the whole box toward you. The left stop will come out of its slot.
  3. Disconnect the damper arm on the right (the white plastic ring-type pivot) by simply pulling the glove box downward.
  4. Squeeze the right side wall inward and lower the glove box all the way down. It will hang on its hinges.
  5. Behind the glove box you will see the cabin air filter cover. Pull the right-hand cover latch toward you with a finger. The left latch will release automatically.
  6. Open the cover and remove the old filter. (You may need a flat-blade screwdriver if the filter is stuck from moisture.)
  7. Wipe dust and leaves out of the filter housing with a dry rag.
  8. Install the new filter with the arrow pointing down (the airflow direction is marked on the edge of the filter).
  9. Close the cover until the latches click.
  10. Put the glove box back: lift it up, reconnect the damper on the right, and insert the left and right stops until they click.

Common mistakes and warnings

  • Do not install the filter against the arrow, as this reduces filtering efficiency. In heavily polluted conditions (pollen, leaves, moisture), replace the filter more often than the scheduled interval. A clogged filter weakens airflow and puts extra load on the climate control blower motor.
