2017-2021 Maserati Quattroporte Rear Console Switch: Fixing Sunshade & Heated Seat Failures
A complete guide to diagnosing, replacing, and buying a used rear console switch cluster for the 2017-2021 Maserati Quattroporte.
- The most common cause of failure is simple electronic wear or liquid spills; symptoms are unresponsive buttons for the rear sunshade or heated seats.
- Replacement is an extremely easy DIY job, requiring only a plastic trim tool and about 15-20 minutes.
- Before buying a used part, verify your vehicle has the required options and match the OEM part number 670080291 exactly.
- No recalls or TSBs are specific to this switch, but electrical issues are a known characteristic of this Maserati generation.
Symptoms of a Failing Rear Console Switch
Failure of the rear console switch cluster is typically straightforward. Because it's a simple input device, the symptoms are directly related to the functions it controls. You won't typically see check engine lights, but you will notice a loss of convenience features.
- Rear Window Sunshade Inoperative: The most common symptom is the rear sunshade failing to raise or lower when the button is pressed. The button may feel physically normal, but nothing happens.
- Rear Heated Seats Won't Turn On/Off: The heated seat buttons may not respond when pressed. The indicator light on the switch may fail to illuminate, and the seat will not heat up. In some cases, the switch might fail in the 'on' position, though this is less common.
- Intermittent Functionality: Before complete failure, the switch may work sporadically. This can be a sign of failing internal contacts. Sometimes, pressing the button multiple times or with extra force might make it work temporarily.
- Dead or Flickering Indicator Lights: The small LED lights that show when a function is active may burn out or flicker, even if the switch itself still works. This is a failure of the switch's internal circuit board.
- No Response from Any Buttons: If none of the buttons on the panel work, it could indicate a total failure of the switch unit or a loss of power to the connector itself.
Pro Tip: Spilled liquids are a primary cause of failure for console-mounted electronics. If you are diagnosing a dead switch, check the connector and the area around the switch for sticky residue or corrosion, which is a clear sign of liquid damage.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Maserati or the NHTSA that directly address the rear console switch cluster for the 2017-2021 Quattroporte.
However, it's important to note that this generation of Maserati vehicles has been subject to several recalls for other electrical system components, including seat wiring harnesses, backup cameras, and engine control software. General electrical issues affecting infotainment systems and various control modules are among the most common owner complaints for these vehicles. While the rear switch itself is not a specific recall item, its failure fits the broader pattern of electrical component sensitivity in these cars.
Step-by-Step Replacement Guide
Replacing the rear console switch is a simple DIY task that requires minimal tools. The difficulty is very low, and it can be completed in under 20 minutes.
Tools Needed:
- Plastic trim removal tool
Procedure:
- Access the Switch: The switch cluster is located on the rear of the main center console, facing the back seats.
- Pry Out the Switch Panel: Carefully insert a plastic trim removal tool into the seam between the switch panel and the console housing. Gently pry upwards or outwards to release the retaining clips. Work your way around the panel to avoid scratching the console or cracking the switch housing.
- Disconnect the Electrical Connector: Once the switch is loose, pull it out just enough to access the wiring. There will be a single electrical connector on the back. Press the release tab on the connector and pull it straight out to disconnect it.
- Install the New Switch: Plug the electrical connector into the new switch panel. You should hear a click as it seats securely.
- Seat the New Panel: Align the new switch panel with the opening in the console and press it firmly into place. The retaining clips will snap in, securing the panel.
- Test the Functions: Turn the vehicle's ignition to the 'ON' or 'ACC' position. Test all buttons on the new switch—the rear sunshade and both heated seats—to confirm they are working correctly.
Buying a Used Rear Console Switch Cluster
Purchasing a used OEM switch cluster is a cost-effective way to restore functionality. Given the high cost of new Maserati parts, a recycled part offers significant value. Here’s what to look for:
- Verify the Part Number: The most critical step is to match the OEM part number. The primary number for this component is 670080291. Ensure the part you are buying has this exact number.
- Check for Vehicle Options: This switch panel was only fitted to Quattroporte models equipped with the optional rear window sunshade and rear heated seats. Before buying, confirm your vehicle has these features. A VIN check or visual confirmation of the sunshade and seat heating elements is recommended.
- Inspect for Physical Damage: Carefully examine photos of the used part. Look for deep scratches, cracks in the housing, and wear on the button graphics. Avoid any units with visible signs of liquid damage, such as staining or corrosion on the casing or connector pins.
- Seller Reputation: Buy from a reputable seller with a good return policy. Ask if the part was tested before being removed from the donor vehicle.
Warning: Do not purchase a switch from a vehicle that did not have the same options as yours. While it might physically fit, it will not be able to control features that are not wired into your car's Body Control Module.

Frequently Asked Questions (FAQ)
Can I add a rear sunshade or heated seats to my car by just installing this switch?
No. Installing the switch alone will not add these features. Your vehicle must already have the sunshade motor, heated seat elements, and all the necessary factory wiring and programming in the Body Control Module (BCM) for the switch to function.
Is any programming required after installing a new switch?
No. This is a simple plug-and-play component. The vehicle does not need to be reprogrammed after swapping the switch cluster.
The lights on my switch don't work, but the buttons do. Do I need a new switch?
Only if the lack of illumination bothers you. The button function and the backlight are separate circuits on the internal board. A failed LED does not mean the switch itself will fail soon, but it does indicate a partial failure of the unit. Replacement is the only way to restore the light.
My sunshade is stuck up. Is it the switch or the motor?
It could be either. The switch is the easiest and cheapest part to test first. If a known-good switch doesn't solve the problem, the issue likely lies with the sunshade motor, its wiring, or the Body Control Module. A low battery can also cause electronic modules in a Maserati to behave erratically, so ensure your battery is fully charged before diagnosing parts.
