2024-2025 Kia EV9 HVAC Control: Screen Quirks, Symptoms, and Replacement Guide
An in-depth look at the common software-related issues, failure symptoms, and replacement costs for the 2024-2025 Kia EV9's integrated climate control panel.
- Most reported 'problems' with the 2024-2025 EV9 HVAC control are software quirks, like settings not saving, not hardware failures.
- The OEM part number is 97480DO000CRF, which appears to be the complete center vent and screen assembly.
- When buying a used unit, carefully inspect the screen for scratches or damage and verify the part number.
- Replacement may require software calibration by a Kia dealer to ensure full functionality.
Symptoms of a Failing HVAC Control
Because the Kia EV9 is a new vehicle, widespread hardware failures are not yet common. Many reported issues are software-related quirks. However, a failing control unit can still manifest in several ways, ranging from inconvenient to system failure.
- Unresponsive or Frozen Screen: The dedicated 5-inch climate screen or the climate menu on the main infotainment display may become frozen or stop responding to touch inputs. In some cases, a system reset may temporarily fix this.
- Climate Settings Reverting to Default: A common owner complaint is that climate settings do not save after the vehicle is turned off. The system may default to a specific temperature (e.g., 72°F or 80°F) and turn the A/C on every time the car starts, regardless of the previous setting.
- Incorrect Temperature or Airflow: The unit may fail to blend hot and cold air correctly, resulting in air that is always hot or always cold, and does not match the set temperature. Similarly, it may fail to direct air to the proper vents (defrost, dash, or floor).
- Fan Speed Issues: The blower fan may get stuck on one speed, fail to adjust, or not turn on at all. One owner reported front fans not blowing while rear fans continued to operate.
- Remote Climate Start Failure: Owners have reported that the "Start Climate" function in the Kia Connect app frequently fails, especially after the vehicle has been sitting overnight. This is typically a software or connectivity issue rather than a hardware failure.
- A/C Blows Hot Air: While this can be caused by many components like the compressor or low refrigerant, a faulty control module can fail to send the correct signal to engage the A/C compressor.
Known Issues, Recalls, and TSBs for the 2024-2025 Kia EV9
As a new model, the EV9 has had several software updates and a few recalls, though none directly target the HVAC control module for hardware failure.
- Software Quirks: The most prevalent owner complaints involve software behavior. This includes the aforementioned climate settings not saving and issues with the "auto defog" system causing sudden, unexpected blasts of cold air. These are typically addressed through dealer-installed or Over-The-Air (OTA) software updates.
- Design Quirk - Screen Position: Many owners and reviewers note that the dedicated 5-inch climate screen is partially obscured by the steering wheel, requiring the driver to look around it to see all the information. 🎬 See this walkthrough of the EV9 climate controls and charging features.
- Recalls (Unrelated to HVAC Control): The 2024-2025 EV9 has been subject to recalls for issues such as inadequate headliner impact protection, missing second and third-row seat bolts, and software problems with the Remote Smart Parking Assist (RSPA) and the main digital instrument cluster. These recalls do not involve the climate control system itself.
- Technical Service Bulletins (TSBs): Kia has issued multiple TSBs for the EV9 to improve software logic for various systems, including charging management, power seats, and headlamps. If you are experiencing persistent software-related climate issues, it is worth checking with a dealer to see if a new software update is available. 🎬 Watch: Stay updated on the latest Kia EV9 recalls and software news.
Pro Tip: If your infotainment or climate screen freezes, you can perform a hard reset. Use a ballpoint pen or similar object to press the small, recessed button located to the left of the volume/power roller knob. Press and hold it for a few seconds until the screen goes blank and reboots. This often resolves temporary software glitches without affecting your settings.

Given the vehicle's age, most replacements will be covered under the factory warranty. However, if you need to purchase a replacement due to accidental damage, buying a used OEM unit is a cost-effective option. Aftermarket versions are not available for this model.
- Verify the Part Number: The primary part number for the center climate control and vent assembly is 97480DO000CRF. Always match this number exactly to ensure compatibility.
- Inspect the Screen Carefully: This is the most critical inspection point. Look for deep scratches, cracks, or any signs of delamination on the 5-inch display. Power it up if possible to check for dead pixels or discoloration.
- Check Physical Controls: Test the physical toggle switches for temperature control. They should have a solid, tactile click and not feel loose or sticky.
- Examine Connectors: Check the electrical connectors on the back of the unit. Ensure no pins are bent, broken, or corroded. The plastic housing should be free of cracks.
- Source from a Low-Mileage Vehicle: Since these are new vehicles, try to source a part from a donor car with the lowest possible mileage. This minimizes the chances of wear and tear on the screen and electronics.
Cost Comparison
The following table breaks down the estimated costs for replacing the EV9's HVAC control unit. Note that the OEM part number appears to include the vent assembly and the integrated screen.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Dealer) | $150 - $225 |
| Used OEM (Recycled) | $75 - $150 (when available) |
| New Aftermarket | Not Available |
| Shop Labor | $125 - $250 |
Replacement Overview
Replacing the HVAC control unit is moderately difficult and requires careful work to avoid damaging the dashboard.
- Difficulty: 2 out of 5
- Estimated Time: 1-1.5 hours
- Tools Needed: Plastic trim removal tools, socket set.
The basic process involves using plastic pry tools to carefully remove the dashboard trim surrounding the control unit. Once the trim is off, the unit is typically held in by a few screws. After disconnecting the electrical harnesses, it can be removed.
Warning: While a physical swap may be straightforward, the vehicle's complex electronics may require the new module to be calibrated or programmed by a Kia dealer to ensure full functionality with the rest of the vehicle's systems. Always factor in a potential dealer visit when replacing electronic modules on a new vehicle like the EV9.
Frequently Asked Questions (FAQ)
Does a replacement HVAC control on a Kia EV9 need to be programmed?
It is highly likely. On modern vehicles, new electronic modules often need to be programmed or calibrated by the dealer to communicate correctly with the vehicle's other computers. While a used unit might work on a plug-and-play basis, you should be prepared for a potential dealer visit to ensure all features work correctly.
Why do my climate settings keep resetting every time I start the car?
This is a common software issue reported by many 2024-2025 EV9 owners. It is not a sign of a hardware failure. The issue is often tied to how the system interacts with driver profiles. Check with your Kia dealer for any available software updates (TSBs), as these are often released to fix such logical quirks.
How can I fix an unresponsive or frozen climate screen?
First, try a system reset. Use a pen to press and hold the small pinhole reset button next to the volume knob for a few seconds until the system reboots. If this does not solve the problem, the issue could be a deeper software fault or a hardware failure requiring diagnosis by a technician.
Is the A/C blowing hot air a problem with the control module?
It can be, but it's not the most likely cause. More common reasons for an A/C system blowing hot air are a refrigerant leak or a failed A/C compressor. However, if the control module fails to send the signal to turn the compressor on, it would cause the same symptom. A professional diagnosis is needed to pinpoint the exact cause.
