2021-2024 Hyundai Elantra Ventilator Lever TSB

Hyundai has released Technical Service Bulletin (TSB) 25-HA-001H to address common heating, ventilation, and air conditioning (HVAC) concerns in certain 2021-2024 Elantra vehicles. This bulletin details the inspection and replacement procedure for the Hyundai Elantra ventilator lever, which can cause various airflow and noise issues.

Symptoms

Owners of affected Hyundai Elantra models may experience one or more of the following conditions related to the HVAC system:

• A noticeable lack of airflow coming from the forward-facing center vents.
• The mode actuator failing to change airflow direction correctly after various inputs.
• A distinct popping or snapping noise heard when switching between different HVAC modes.

Applicable Vehicles

This TSB applies to the following vehicles:

Year	Make	Model
2023	Hyundai	Elantra
2024	Hyundai	Elantra
2022	Hyundai	Elantra
2021	Hyundai	Elantra

Specifically, it covers 2021-2024MY Elantra (CN7) models produced between December 24, 2020, and November 28, 2023 (VINs starting with 'KMH'), and 2021-2023MY Elantra (CN7A) models produced between September 25, 2020, and May 25, 2023 (VINs starting with ‘5NP’).

Diagnosis / Trigger Conditions

To diagnose if the Hyundai Elantra ventilator lever is the cause of the HVAC issues, technicians will perform a specific inspection:

1. The A/C or heater system is turned ON.
2. The airflow is set to floor mode only.
3. The mode actuator is then changed to the forward-facing vent mode.
4. The technician verifies if airflow is present from the center vents.

If no airflow is present from the forward-facing center vents, or if a popping/snap noise is heard when switching modes, the ventilator lever needs replacement. However, if airflow is present but other concerns exist, this TSB does not apply, and further diagnosis according to the shop manual is required.

Repair Procedure Summary

The repair involves replacing the ventilator lever. The general steps include:

1. Recording the customer's audio presets and disconnecting the negative battery terminal.
2. Removing the main crash pad assembly, which requires careful attention to avoid damage.
3. Disconnecting the passenger's airbag (PAB) connectors.
4. Locating and removing the mode door actuator and cam mode guide.
5. Removing the ventilator lever screw and the old ventilator lever arm.
6. Transferring the screw and washer from the old lever to the new part, then reinstalling the new ventilator lever onto the HVAC box.
7. Documenting the repair by taking a photo of the old ventilator lever arm with the last six digits of the VIN and the repair date, then uploading it to STUI (Service Technical Update Information).
8. Inspecting the floor door lever position and correcting it if it's horizontal.
9. Reinstalling the cam mode guide, actuator, and the main crash pad.
10. Reinstalling all other components in the reverse order of removal.
11. Finally, verifying the proper operation of the heating and air conditioning vents.
