2023-2024 Kia Telluride Rear Dome Light & Climate Control: Diagnosing Failures and Control Issues

Symptoms of Failure

When the rear overhead control panel in a 2023-2024 Telluride begins to fail, the issues are most often related to the climate control functions rather than the lights. Because the vehicle is so new, widespread component failure is not yet common, but some owners have reported specific problems. Many other perceived issues are often simple user misunderstandings of the vehicle's features.

Most Common Reported Problems

• Unresponsive Rear Climate Controls: Buttons on the panel may not respond when pressed, preventing passengers from adjusting the rear temperature or fan speed.
• Erratic Fan Speed: Some owners report the rear fan only works on the highest setting (speed 8) and does not produce airflow at lower settings. This points to a potential failure within the panel's electronic controls or a related blower motor resistor.
• System Activates on Its Own: In some cases, the rear climate control may turn itself on without user input, sometimes even after the vehicle has been parked and turned off. This suggests a short or fault within the control module's logic board.
• Inoperative Dome or Map Lights: The lights housed within the unit may flicker, fail to turn on with the button presses, or not illuminate when the doors are opened. In some instances, this has been traced to a deeper electrical issue like a faulty junction box rather than the light assembly itself.

Issues Mistaken for Part Failure

• No Heat from Overhead Vents: The Telluride's HVAC system is designed to deliver heat primarily through floor-level vents, while the overhead vents are mainly for air conditioning. It is normal for the overhead vents to blow cool or ambient air even when the system is set to heat.
• Delayed Rear Heat: It can take several minutes for warm air to reach the rear vents after the vehicle starts, which is normal system behavior.

Known Issues, TSBs, and Recalls

As of mid-2024, there are no specific Technical Service Bulletins (TSBs) or recalls from Kia or the National Highway Traffic Safety Administration (NHTSA) for the rear dome light and climate control assembly on 2023-2024 Telluride models.

While several recalls exist for these model years, they pertain to other systems:

• NHTSA Campaign 23V298000 (Kia SC270): A software issue that could cause the digital instrument cluster to go blank.
• NHTSA Campaign 23V075000 (Kia SC262): Improperly installed side airbag wire harnesses.
• NHTSA Campaign (Kia SC316): A fire risk associated with the front power seat motor overheating.

These recalls are not related to the function of the interior lighting or rear climate controls.

Buying a Used 2023-2024 Telluride Rear Control Panel

Since this is a combined electronic module, buying a tested, recycled OEM part is often the most cost-effective solution. Aftermarket copies for such a specific, new part are generally not available. Here’s what to look for when buying used.

What to Check Before You Buy

1. Verify The Part Number: This is the most critical step. The primary part number for this assembly is 97950-S9810. It may have a suffix like GYT or WKQQK depending on the interior color. Part number 92850-S9100 is for the older 2020-2022 models and is not compatible. Double-check the number on your original part before ordering.
2. Inspect All Buttons: Physically press every button on the panel (fan speed up/down, temperature, mode, lights). They should all have a firm, tactile click and should not be loose, sticky, or pushed into the housing.
3. Check the Lens Covers: Ensure the plastic lenses for the dome and map lights are not cracked, hazy, or covered in deep scratches.
4. Examine the Electrical Connector: Look at the connector port on the back of the unit. The pins should be straight, clean, and free of any green or white corrosion.
5. Ask About the Source Vehicle: Because these are new models, most used units will come from vehicles involved in collisions. This means the part itself is likely to have very low mileage and wear. It's a good sign if the seller can confirm it came from a vehicle with no interior fire or water damage.

Cost Comparison

Replacing the entire assembly is usually necessary if the electronic controls have failed. Here is an estimated cost breakdown:

Replacement Guide (Difficulty: 1/5)

Replacing the rear overhead control panel is a straightforward task that most DIYers can complete in under 30 minutes.

Tools & Materials Needed:

• Plastic trim removal tool set
• Clean microfiber cloth

Step-by-Step Replacement

1. Safety First: Although not strictly necessary for a low-voltage part, it's always a good practice to disconnect the negative terminal of the 12V battery before working on vehicle electronics.
2. Pry the Assembly Down: Using a plastic trim removal tool to avoid scratching the headliner or plastic, carefully insert the tool at the edge of the assembly (usually the side closest to the windshield) and gently pry downwards. The unit is held in by clips.
3. Disconnect the Wiring: Once the assembly is loose, lower it until you can see the electrical connector on the back. Press the release tab on the connector and pull it straight out to disconnect it.
4. Install the New Unit: Plug the electrical connector firmly into the new/replacement assembly. You should hear it click into place.
5. Seat the Assembly: Align the clips on the new unit with the slots in the headliner and press firmly upwards until it snaps securely into place.
6. Test the Functionality: If you disconnected the battery, reconnect it. Turn the vehicle on and test every button on the panel—lights, fan speeds, and temperature controls—to ensure everything is working correctly.
