2020-2022 Kia Telluride Master Window Switch: Why Windows, Locks & Mirrors Fail
This guide covers the common failures, part number variations, and replacement costs for the driver's door master switch in the 2020-2022 Kia Telluride.
- The most critical step is verifying compatibility. You must match the part number to your Telluride's options, specifically whether it has memory seats and power-folding mirrors.
- Common failure symptoms include non-working windows (especially the driver's), loss of the auto up/down feature, and unresponsive lock or mirror controls.
- There are no specific recalls for the switch itself, but owner complaints of erratic window behavior are common.
- A used OEM switch is a reliable and cost-effective alternative to an expensive new dealer part, often saving several hundred dollars.
Symptoms of a Failing Master Window Switch
When the master window switch in a 2020-2022 Kia Telluride begins to fail, it can cause a range of frustrating electrical issues. Because the switch controls multiple functions, symptoms can vary widely.
- Intermittent or Total Window Failure: The most common symptom is when one or more windows stop responding. The driver's window is often the first to fail. You might find that the window works sporadically or not at all.
- Loss of Auto Up/Down Function: The one-touch auto up/down feature may stop working for the driver or passenger window. Sometimes, this can be temporarily fixed by restarting the vehicle or performing a reset procedure, but persistent failure often points to the switch.
- Inability to Control Other Windows: You may lose the ability to control passenger windows from the driver's door panel, even if the individual switches on the other doors still work.
- Unresponsive Door Lock or Mirror Controls: Since the door lock and side mirror controls are part of the same assembly, they may also become unresponsive.
- Windows Roll Down on Their Own: Some owners have reported that windows will unexpectedly roll down, particularly at highway speeds. This can be caused by the switch's anti-pinch feature misinterpreting wind buffeting as an obstruction.
- Temporary Fix by Slamming Door: In some forum reports, owners noted that slamming the driver's door could temporarily restore function. This strongly suggests a loose internal connection within the switch assembly. 🎬 See this guide on how to repair an inoperative Kia window switch.
Pro Tip: If only one passenger window is not working from the master switch, but works from its own switch, the problem is almost certainly in the master switch. If a window doesn't work from either switch, the issue is more likely the window motor, regulator, or wiring.
🎬 Watch: How to diagnose if the window switch or motor is bad.Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Kia directly addressing a widespread failure of the master window switch for the 2020-2022 Telluride. However, numerous owner complaints have been filed with the National Highway Traffic Safety Administration (NHTSA) regarding erratic window behavior.
It is important not to confuse window switch issues with other active recalls for this vehicle:
- NHTSA Recall SC316: This recall is for a fire risk due to an overheating front power seat motor, caused by a stuck slide knob. Kia advises owners to park outside until this repair is performed. This is unrelated to the window switch but involves an electrical component in the driver's seat area.
- Driveshaft Roll-Away Risk: A recall was issued for 2020-2024 models where the front driveshaft may not be fully engaged, potentially causing the vehicle to roll away while in Park.
Buying a Used 2020-2022 Telluride Master Window Switch
Purchasing a used OEM master switch is a cost-effective way to restore full functionality to your Telluride. However, careful verification is essential to ensure you get the right part. Aftermarket options for this complex, integrated switch are rare and may lack the precise fit and functionality of an original part.
Warning: Compatibility is critical. The Telluride was offered with different master switches depending on vehicle options. Ordering the wrong one will result in features not working.
How to Verify Compatibility
Before purchasing, you must match the part to your vehicle's specific trim and options. There are two primary versions of this switch:
- For models WITH Memory Seats AND Power-Folding Mirrors: The correct OEM part number is typically 93570-S9000. This is common on higher trim levels like the EX and SX.
- For models WITHOUT Power-Folding Mirrors: The correct OEM part number is typically 93571-S9000. This is found on lower trim levels.
Always check the part number on your original switch before ordering. The number is printed on a sticker on the side or bottom of the switch housing. You will need to remove the door panel to see it.
What to Inspect on a Used Switch
- Check the Buttons: Look for excessive wear on the button graphics. While cosmetic, it can indicate very high usage. Ensure all buttons depress and return smoothly.
- Inspect Mounting Tabs: The plastic housing has several mounting tabs and clips that secure it to the door panel. Make sure none of these are broken or cracked, as this will cause a loose fit.
- Examine the Connector Port: Look inside the electrical connector port for any signs of corrosion, bent pins, or heat damage (discoloration).
Cost Comparison
The master window switch for the Telluride is a relatively expensive component when purchased new from a dealer. This makes a quality used OEM part an excellent value.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Dealer) | $350 - $580 |
| New Aftermarket | Not commonly available |
| Used OEM | $70 - $120 |
| Shop Labor Cost | $100 - $150 |
Installation Guide
Replacing the master window switch is a straightforward job for a DIYer with basic tools. The difficulty is rated 2 out of 5 and typically takes 30-60 minutes.
Required Tools:
- Plastic trim removal tool kit
- Phillips head screwdriver
- Small flathead screwdriver (optional)
Step-by-Step Replacement
- Disconnect the Battery: Before working on any electrical components, disconnect the negative terminal from your vehicle's battery.
- Remove Interior Trim Pieces: Use a plastic pry tool to carefully pop off the triangular trim piece near the side mirror (the sail panel). Next, pry open the small cover inside the door pull handle and the cover behind the interior door latch handle to expose the screws.
- Remove Door Panel Screws: Unscrew the Phillips head screws you just exposed. There is typically one in the door pull cavity and one behind the latch handle.
- Pry the Door Panel Loose: Starting from the bottom, use a trim removal tool to pop the plastic clips holding the door panel to the door frame. Work your way around the sides. Once all clips are loose, lift the panel up and off the window ledge. 🎬 Watch: A step-by-step walkthrough on how to take a door panel off.
- Disconnect Cables and Connectors: The door panel will still be attached by electrical connectors and the door latch cables. Carefully unclip the electrical harnesses for the window switch, speaker, and any other accessories. Then, release the two cables from the interior door handle mechanism. Set the door panel aside on a soft surface.
- Remove the Old Switch: The master switch is held into the door panel with several Phillips head screws from the back. Unscrew these, and the switch assembly will come free.
- Install the New Switch: Place the new switch into the door panel and secure it with the screws.
- Reassemble: Reconnect the door handle cables and all electrical connectors to the door panel. Hang the panel back on the window ledge, then press firmly around the perimeter to engage all the plastic clips. Reinstall the screws and cover pieces.
- Reconnect Battery and Test: Reconnect the negative battery terminal. Turn the vehicle on and test all functions on the new switch: all windows (including auto up/down), door locks, and mirror adjustments. You may need to reset the auto up/down function by holding the button down for 5 seconds after the window is fully open, and then holding it up for 5 seconds after it is fully closed.
Frequently Asked Questions (FAQ)
Do I need to reprogram a new window switch?
No, a replacement switch for a 2020-2022 Telluride does not typically require dealer programming. However, you may need to re-initialize the 'auto up/down' window feature. You can do this by running the window all the way down while holding the button, and then all the way up while holding the button.
Why do only my passenger windows not work from the driver's door?
First, check that the 'window lock' button isn't engaged. If it is not, and the windows work from their individual switches, the fault lies within the driver's master switch assembly. The internal contacts for those specific buttons have likely failed.
Can I just replace one bad button on the switch?
No, the master switch is sold as a single, sealed electronic assembly. The individual buttons are not available separately, and attempting to repair the internal circuit board is not practical. The entire unit must be replaced.
My window got stuck down. How can I get it up before I can get a new switch?
Some owners have had temporary success by opening and firmly closing (or slamming) the driver's door, which can sometimes jolt a loose internal connection. If this doesn't work, you will likely need to remove the door panel and apply direct 12V power to the window motor terminals to raise it.
