Is your sun visor flopping down into your line of sight while driving? There aren’t too many things more annoying (and dangerous) than a sun visor that won’t stay up while driving.
Whether it’s slowly sliding down or just completely drops, there are several reasons why this happens and multiple ways to fix it. The good news is that most visors can be fixed in a DIY manner.
How Sun Visors Work
Before getting into the causes and fixes, it helps to understand how sun visors work. Most vehicle sun visors use a friction hinge mechanism that allows the visor to rotate and stay in position. This mechanism typically consists of a metal rod or pivot point with some type of tension device.
When you move your sun visor up or down, you’re working against this tension, which is designed to hold the visor wherever you place it. The tension comes from either a spring system, friction clips, or specially designed hinges that create enough resistance to hold the visor in place.
Many modern vehicles also have extendable or sliding visors that provide additional coverage (a feature many drivers aren’t aware of). These have their own set of mechanics, usually involving plastic tracks and clips that can wear out over time.
The primary components that can fail include the friction hinges, internal springs, plastic clips, or the mounting hardware that attaches the visor to the headliner. When any of these parts wear out or break, your once-reliable sun visor becomes an unpredictable nuisance.
Common Causes of Sun Visors Not Staying Up
Let’s look at the most common reasons your sun visor keeps falling down and how to resolve each issue.
1) Worn Out Friction Hinges
By far the most common reason for a sun visor that won’t stay up is worn-out friction hinges. These hinges rely on tension to hold the visor in place. Over time and with repeated use, the friction material inside the hinge wears down, reducing the tension that keeps your visor in position.
The more you use your visor, the more likely you’ll have a problem down the road. The biggest clue that you have this problem is if the visor gradually slides down instead of suddenly dropping, or if it only stays up when positioned at certain angles.
Most modern vehicles (especially those made in the last 10-15 years) primarily use friction hinge systems rather than spring mechanisms.
How to Fix
- Tighten the hinge screws. Many visor hinges have visible screws that can be tightened. Locate the screws (usually on the mounting bracket near the roof) and gently tighten them with a small screwdriver. Be careful not to overtighten as this could strip the screws or crack the plastic.
- Add friction material. If tightening doesn’t help, you can use your MacGyver skills (I’m aging myself) to increase the friction by inserting thin material like a piece of rubber, cardboard, or even a folded piece of duct tape between the visor and its mount. This adds resistance and might provide enough tension to keep the visor in place.
- Replace the hinge. For a more permanent solution, you can replace the friction hinge entirely. This usually requires removing the visor (typically held in by screws or clips) and installing a new hinge assembly. Replacement hinges can be found at auto parts stores or ordered online for your specific vehicle make and model.
2) Broken Internal Springs or Clips
The second most common cause is broken internal springs or plastic clips inside the visor assembly. This issue is more common in older vehicles or specific models that use a spring and detent system rather than purely friction-based mechanisms.
In these designs, small springs or plastic retention clips help hold the visor in specific positions. When these components snap or break, your visor loses its ability to stay in position.
You can identify which mechanism your vehicle uses by how the visor fails: if your visor suddenly drops without warning or if it only holds in very specific positions (like fully up or fully down with nothing in between), you likely have a spring/clip system rather than a friction hinge.
In some cases, you may also hear a rattling sound inside the visor when you move it. This problem often occurs after years of use or in vehicles regularly exposed to extreme heat, which can make plastic components brittle.
How to Fix
- Open the visor cover. Some visors have a fabric or vinyl cover that can be carefully removed with a seam ripper to access the internal components. Work slowly around the edges to avoid damaging the material.
- Replace broken springs or clips. Once inside, you can identify and replace any broken springs or clips. Small springs can sometimes be found at hardware stores, while specific plastic clips might need to be ordered from a dealer or auto parts supplier.
- Reassemble the visor. After fixing the internal components, carefully glue or sew the cover back in place. Use an appropriate adhesive that can withstand heat, or sew with a heavy-duty thread that matches the visor color.
- Full replacement. If the internal damage is extensive or you simply don’t want to deal with this type of repair, replacing the entire visor assembly might be more practical.
3) Loose (or Damaged) Mounting Hardware
Another area to look at is where the hardware connects your sun visor to the car’s roof. This includes screws, bolts, or the mounting bracket itself. Over years of use, these components can loosen from vehicle vibration or become damaged from forceful handling.
If your entire visor assembly moves or feels wobbly when you touch it, or if the visor tilts at an unusual angle, loose or damaged mounting hardware is what you’re likely dealing with. This problem is especially common in older vehicles or those driven frequently on bumpy roads.
How to Fix
- Tighten existing hardware. Use a screwdriver to carefully tighten any visible screws or bolts at the mounting point. Most visor mounts have at least one or two screws accessible from the outside.
- Replace stripped screws. If the screws spin freely without tightening, they may be stripped. Remove them and replace with slightly larger screws or use a thread repair kit or inserts. Just be careful not to use screws that are too long, as they could penetrate the headliner.
- Reinforce the mounting area. If the mounting area itself is damaged, you may need to reinforce it. Small metal plates or washers can distribute pressure more evenly and provide additional support.
- Replace the mounting bracket. If the bracket is bent or broken, you’ll need to replace it entirely. These parts can usually be ordered from dealerships or found at salvage yards if you have one near you. Installation typically requires removing the old bracket and securing the new one with the appropriate hardware.
- Use automotive-grade adhesive. For temporary fixes or when hardware replacements aren’t possible, high-strength automotive adhesive can help secure loose components. Make sure to clean all surfaces thoroughly before applying adhesive.
4) Physical Damage and Heat Deterioration
Actual physical damage and heat-related deterioration of the visor components is another possibility. The core of most visors is made from foam or cardboard-like material covered with fabric or vinyl, while the mounting hardware is typically plastic.
Both the body and mounting components can break, warp, or deform, especially in vehicles exposed to extreme temperatures or humidity.
You can identify this problem if your visor appears bent, has visible cracks, feels unusually brittle, or if the mounting points look deformed. This type of damage is particularly common in older vehicles or those regularly parked outdoors in harsh weather conditions.
Cars and trucks with with dark interiors, no window tint, or those parked in direct sunlight are especially at risk, as interior temperatures can exceed 150°F on hot days.
How to Fix
- Reinforce the visor core. For minor warping or bending, you can reinforce the visor by inserting a thin piece of plastic or cardboard inside. This often requires carefully opening a seam (again using a seam ripper), inserting the reinforcement material, and then resealing the visor.
- Repair breaks with adhesive. If the visor core is cracked or broken, you can use an epoxy adhesive designed for plastic to repair it. Make sure to use adhesives specifically designed for automotive use that can withstand high temps, as regular household glues will likely fail in extreme heat.
- Reshape with heat (for plastic components). Some plastic parts can be gently reshaped when warmed. Use a heat gun (a hair dryer can also work) to warm the plastic, carefully reshape it, and then allow it to cool while held in the desired position.
- Replace damaged components. For severe damage or components that have become brittle from heat exposure, replacement is often your only solution. Factory replacements can be purchased from dealerships or online, while aftermarket options are available at lower prices (typically lower quality though).
Extend the Life of Your Sun Visors
Keeping a component like your sun visor in good working condition is much easier than fixing it after it breaks. Here are a few easy tips that can extend the life of your visors:
- Handle with care: When adjusting your sun visor, use gentle pressure rather than forcefully pushing or pulling it. Grab it by the body of the visor rather than the edges or corners, which can break more easily.
- Use both hands: When possible (not while the vehicle is in motion), use both hands to move your visor (one to hold the mounting area and one to reposition the visor). This reduces stress on the hinge mechanism.
- Park in shade when possible: Regular exposure to intense heat can damage the plastic components and adhesives in your visor assembly (as well as any other plastic components on your car). Parking in a shaded area or using a windshield sunshade can significantly extend the life of all interior components.
- Clean occasionally: Dust and dirt can work their way into hinge mechanisms and increase wear. Gently wipe down your visors with a damp cloth every few months to keep them clean.
- Don’t ignore problems: If you notice your visor beginning to sag or not hold position as firmly as it once did, address the issue early. Minor adjustments or repairs can prevent more serious damage.
- Don’t hang items from visors: Those sunglasses holders that clip onto visors might be convenient, but the added weight stresses the hinge mechanism and can lead to premature failure.
