Four Seasons HVAC Recirculation Door P/N:73488
Switch cleanly between fresh outside air and recirculated cabin air with the Four Seasons HVAC Recirculation Door 73492 — the direct-fit answer for anyone searching a Jeep wj recirculation door. It drops in as a replacement for the 1999-2004 Jeep Grand Cherokee; see the "Vehicles it fits" section for engine-level fitment.
Inside the HVAC air-intake housing, this movable door redirects the blower's airflow between the outside-air inlet and the recirculation path. When the original door cracks or its pivot wears out, the system may stop switching modes and you may hear a clicking or knocking from behind the dash — signs this part may need replacing. Diagnose the cause before replacing.
For a 1999-2004 Jeep Grand Cherokee recirculation door repair, this replaces the failed flap and its actuating linkage.
