2020-2022 Kia Telluride Rear Dome Light: Fixing Rattles and Climate Control Faults

Symptoms of a Failing Rear Overhead Console

Problems with this console can be divided into two categories: lighting issues and climate control issues. While a simple bulb can burn out, many symptoms point to a deeper electrical problem within the console or the vehicle's wiring.

Lighting Symptoms

• Dim or Flickering Lights: The dome lights may appear dimmer than usual or flicker intermittently. This can be a sign of a failing LED/bulb, a loose connection within the console, or a broader vehicle electrical issue like a weak battery or alternator.
• Lights Don't Turn On: The lights may fail to illuminate when a door is opened or when the button is pressed. This could be a burnt-out bulb, a faulty switch on the console, or a problem with the door trigger switch.
• Lights Stay On / Turn On Randomly: Some owners report the middle row map lights turning on by themselves and needing to be manually shut off. This often points to an internal fault in the console's switch logic.

Rear Climate Control Symptoms

• Controls Are Unresponsive: The buttons or dials on the overhead console fail to change the fan speed, temperature, or mode for the rear HVAC system.
• Climate Control Turns On By Itself: This is a widely documented issue, particularly on early 2020 models. The rear climate control will activate on its own, often defaulting to a specific fan speed and mode, even after being turned off from the front or rear controls.
• "Vehicle Controller error" Message: When trying to adjust the rear climate settings from the front infotainment screen, an error message may appear, preventing any changes.
• Inability to Retain Settings: The system fails to remember the last used setting after the vehicle has been turned off for a period of time. This is a specific issue addressed by a technical service bulletin.
• Rattling Noises: A persistent buzzing or rattling sound may come from the overhead console area, especially when driving on rough roads. This is caused by either the console's mounting clips or the frame it attaches to.

Known Issues, TSBs, and Recalls

While there are no specific safety recalls for this part, Kia has issued several Technical Service Bulletins (TSBs) and Service Actions to address common complaints related to the rear overhead console.

TSB CLI047: Rear HVAC Control Turns On By Itself

This is the most significant known issue. Early production 2020 Telluride models may have a fault where the rear climate control does not keep its settings and turns on randomly.

• Vehicles Affected: 2020 Kia Telluride produced from January 8, 2019, through June 4, 2019.
• Cause: An issue with the wiring between the main harness and the Integrated Central Control Unit (ICU).
• Solution: TSB CLI047 outlines a procedure for dealers to perform a wire harness upgrade. It involves cutting the red wire at Pin 25 of the MR-11 connector (located in the driver's side A-pillar) and running a new wire to Pin 18 of the ICU junction block. This is a permanent fix for the memory issue. For vehicles out of warranty, this can be a complex DIY repair.

TSB SA534: Rattling from Retaining Clips

Some owners experience a rattle directly from the console itself. This was addressed by a service action.

• Vehicles Affected: 2022-2023 Kia Telluride produced from August 1, 2022, through May 3, 2023.
• Cause: The original metal retaining clips that hold the console to the headliner cross-member can vibrate and create noise.
• Solution: The TSB instructs technicians to replace the two metal retaining clips with updated plastic clips. This is a simple repair that can be done easily once the console is removed.

DIY Rattle Fix: Loose Headliner Mounting Ring

Separate from the clip rattle, a common source of noise is the plastic support ring glued to the headliner itself. Over time, the factory glue can fail, allowing the ring to vibrate against the headliner or the roof structure.

Buying a Used Rear Overhead Console: What to Check

A used OEM console is a cost-effective alternative to a new part, especially since aftermarket versions are not available. However, careful inspection is key to getting a good part.

Compatibility Check

1. Verify the Part Number: There are several part numbers for this console. The number is printed on a sticker on the top of the housing. Match it as closely as possible. The base numbers are often `97950-S9010` or `97950-S9310`. Differences can relate to sunroof controls or other features.
2. Confirm the Color Code: The last three letters of the part number indicate the color. For example, `GYD` or `GYT` typically stand for gray, while `WK` is often used for black. Make sure the color matches your vehicle's interior.
3. Ask for the Donor VIN: If possible, get the Vehicle Identification Number (VIN) from the vehicle the part was removed from. A Kia dealer's parts department can use this to confirm the exact features and original compatibility.

Physical Inspection

• Check All Mounting Clips: Inspect the plastic tabs and metal clips around the housing. Ensure none are broken or cracked, as this will lead to a poor fit and rattles.
• Examine the Wiring Connector: Look at the main electrical connector port. The pins should be straight and free of any corrosion or damage.
• Inspect the Lenses and Buttons: Check the clear plastic light lenses for deep scratches or hazing. Press all the buttons and turn the dials; they should move freely without sticking.

Cost Comparison: New vs. Used

Replacing the rear overhead console can vary in cost depending on the source of the part.

Replacement Guide

Replacing the rear overhead console is a straightforward task suitable for a DIYer with basic tools. The main challenge is not damaging the headliner or the plastic console.

• Difficulty: 1.5 out of 5
• Estimated Time: 15-30 minutes
• Tools Needed: Plastic trim removal tool kit, small flathead screwdriver (optional).

Step-by-Step Instructions

1. Remove Lens Covers (If Applicable): On some units, the clear light lenses can be pried off first to reveal mounting screws or provide a better grip. Use a plastic trim tool to gently pry them off.
2. Pry Down the Console: Insert a plastic trim tool between the headliner and the edge of the console. It's often easiest to start from the rear (end closest to the tailgate).
3. Release the Clips: Work your way around the console, gently prying downwards to release the four main retaining clips. Be prepared for the metal clips to bend slightly during removal; they can be bent back into shape.
4. Disconnect the Wiring: Once the console is free from the headliner, let it hang by the wiring harness. Press the release tab on the electrical connector and pull it straight out to disconnect it.
5. Install the New Console: Connect the wiring harness to the new unit, making sure it clicks securely. Align the console with the opening in the headliner and press it firmly upwards until all the clips snap into place.
