2020-2021 Mazda 6 & Mazda6 Sun Visor: Why It Droops and How to Find the Right Replacement

Common Symptoms of a Failing Sun Visor

A failing sun visor is more than just an annoyance; a visor that droops or hangs down can obstruct your view of the road. Here are the most common signs that your Mazda 6 sun visor needs to be replaced:

• Drooping or Not Staying Up: This is the most frequent failure. The internal pivot mechanism wears out or breaks, losing the tension required to hold the visor in place. This can happen gradually or suddenly. Some owners of similar Mazda models from this era report hearing a loud 'click' or 'snap' noise as the internal plastic fails, often after the car has been sitting in the heat.
• Vanity Light Failure: If the mirror light flickers or doesn't turn on, the issue could be a burnt-out bulb, a faulty switch in the mirror cover mechanism, or a problem with the electrical connector at the mounting point.
• Broken Mirror or Cover: The vanity mirror can crack from impact, and the plastic cover or its small hinges can break from repeated use, preventing it from staying closed.
• Loose Mounting or Rattling: While less common, the screws holding the visor to the headliner can sometimes loosen, causing the entire assembly to feel wobbly or rattle over bumps.
• Cosmetic Damage: The fabric covering the visor can become stained, torn, or begin to separate from the inner board due to age and sun exposure.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

As of mid-2024, there are no official recalls or Technical Service Bulletins (TSBs) from Mazda or the National Highway Traffic Safety Administration (NHTSA) specifically for sun visor failures on the 2020-2021 Mazda 6. However, owner forums for other Mazda models from the same period (like the CX-30) show numerous complaints of visors failing due to heat exposure. Owners report that after being parked in the sun, the visor's plastic components seem to warp or shrink, leading to a snapping sound and subsequent failure to stay up. While not officially acknowledged for the Mazda 6, this suggests a potential material sensitivity to high temperatures across the product line.

Buying a Used 2020-2021 Mazda 6 Sun Visor: What to Check

Purchasing a used OEM sun visor is an excellent way to save money, but careful verification is required to ensure you get the right part. Mismatched features are the number one cause of installation problems.

Step 1: Identify Your Vehicle's Exact Configuration

Before you buy, you must know which version you need. Check your vehicle for the following options:

• Side: Do you need the Left (Driver) or Right (Passenger) side?
• Sunroof: Does your Mazda 6 have a factory sunroof? Visors for cars with and without a sunroof have different mounting bases or shapes and are not interchangeable.
• Illumination: Does your current visor have a vanity light? If it does, you need a replacement with a light to connect to the existing wiring. A non-illuminated visor will not have the electrical plug.
• HomeLink: While less common on these models, check if your driver's side visor has buttons for a built-in garage door opener.

Step 2: Find Your Interior Color Code

Mazda 6 interiors for this generation typically came in Black or Gray/Beige. Ordering the wrong color is a common mistake. The definitive way to know your color is to find the interior trim code on the manufacturer's sticker.

1. Open the driver's side door.
2. Locate the black and white sticker in the door jamb area (the pillar where the door latches).
3. Look for the "TRIM" or "INTERIOR TRIM" code on this sticker. This code specifies your exact interior color.

Step 3: Inspect the Used Visor

When you have the used part in hand, perform these quick checks:

• Test the Hinge: Move the visor up and down. It should feel firm and hold any position without drooping.
• Check the Mirror: Open the vanity mirror cover. Ensure it's not cracked and that its own hinge opens and closes smoothly.
• Examine the Connector: If it's an illuminated visor, look at the electrical connector pins. They should be straight and free of corrosion.
• Look for Damage: Check for any cracks in the plastic base, tears in the fabric, or significant stains.

Sun Visor Replacement Cost (2020-2021 Mazda 6)

Replacing a sun visor is an inexpensive repair, especially if you do it yourself. Aftermarket options for this specific part are not widely available, so your choice is between new OEM and used OEM.

How to Replace the Sun Visor (DIY Guide)

Replacing the sun visor on a 2020-2021 Mazda 6 is a simple DIY task that takes about 10-15 minutes and requires only basic tools.

Tools Needed:

• Small flathead screwdriver or trim removal tool
• Phillips head screwdriver

Step-by-Step Instructions:

1. Expose the Screws: At the base of the sun visor where it mounts to the headliner, there is a small plastic cover. Use a small flathead screwdriver to gently pry this cover off. It will pop open, revealing two Phillips head screws.
2. Remove the Screws: While holding the sun visor with one hand to keep it from falling, use the Phillips screwdriver to remove both screws.
3. Disconnect the Wiring: Gently pull the visor down from the headliner. You will see a small electrical wire connecting it to the car's harness. Press the release tab on the connector and pull it apart. Do not pull on the wires themselves.
4. Install the New Visor: Connect the electrical plug of the new visor to the car's harness. You should hear a click.
5. Secure the Visor: Align the new visor with the mounting holes in the headliner. Hand-start both screws to avoid cross-threading, then tighten them until they are snug. Do not overtighten, as this can crack the plastic base.
6. Replace the Cover: Snap the plastic trim cover back into place over the screws. Test the visor's movement and the vanity light to ensure everything works correctly.

Technical Specifications & Part Numbers

Matching the part number is the best way to guarantee compatibility. The part number is often printed on a sticker on the visor body, which may be hidden by the headliner when installed. Below are some of the known OEM part numbers for the 2018-2021 generation. Note that the final digits can vary based on color and minor updates.
