Car side mirrors are essential for driving safely, providing visibility to what’s behind and to the sides of your vehicle. Unfortunately, they can encounter a variety of issues, from misalignment to complete detachment. Understanding how to address common problems with side mirrors can save you time and money, and prevent potential accidents. This guide will walk you through the most common side mirror issues and how to fix them.
1. Misaligned Side Mirrors
Misaligned mirrors are a frequent issue, often caused by accidental bumps or impacts. When side mirrors are not properly aligned, you lose proper visibility, increasing the risk of accidents.

How to Fix Misalignment:
- Manual Adjustment: For manual mirrors, simply push the mirror in the right direction until you get the correct viewing angle. You may have to make small adjustments while sitting in the driver’s seat.
- Electric Mirror Adjustment: Most modern cars have an electric adjustment switch inside the vehicle. Locate the side mirror adjustment controls (usually near the driver’s window), and adjust the mirror’s position using the switch. Aim for an angle where you can clearly see the side and rear of your car, without turning your head too much.
Tip: For best results, the side mirrors should show a small portion of your car while covering as much road as possible.
2. Broken Side Mirror Glass
A cracked or shattered mirror significantly impairs your driving safety. This issue usually arises due to collisions, road debris, or extreme weather conditions.

How to Replace the Mirror Glass:
- Gather Materials: You’ll need replacement mirror glass (which can be bought at auto parts stores), adhesive glue, and a screwdriver.
- Remove the Broken Glass: Use a flat tool like a putty knife to gently pry away the remaining broken pieces of glass. Be sure to wear gloves for protection.
- Apply Adhesive: Once the broken glass is removed, apply adhesive to the back of the replacement mirror.
- Install the New Mirror: Press the new mirror into the housing firmly, ensuring it fits securely.
Tip: Some cars allow you to replace just the glass, while others may require a complete side mirror replacement. Check your vehicle’s manual before purchasing the parts.
3. Power Mirror Not Working
If your electric side mirrors stop responding to the adjustment switch, you might be facing electrical issues, which could range from a blown fuse to a faulty motor.

Steps to Diagnose and Fix the Issue:
- Check the Fuse: Locate your car’s fuse box (usually under the dashboard) and check the fuse related to the side mirrors. Replace the fuse if it’s blown.
- Inspect the Wiring: If the fuse is intact, the issue could lie in the wiring. Remove the mirror panel and check the wiring for damage or disconnections. Repair or replace any damaged wires.
- Test the Mirror Motor: If the wiring is fine, the motor may be malfunctioning. Test the mirror motor by connecting it to a working power source. If it doesn’t work, you may need to replace the motor.
Tip: If you’re unsure about handling electrical work, consider seeking professional assistance.
4. Loose Side Mirrors
Over time, side mirrors can become loose due to vibration, accidents, or wear and tear. A loose side mirror is not only annoying, but it can also fall off completely if not fixed.

How to Tighten a Loose Side Mirror:
- Inspect the Mounting Bracket: Locate the screws or bolts securing the mirror to the car. These are typically found behind a plastic cover on the side mirror assembly.
- Tighten the Screws/Bolts: Use a screwdriver or wrench to tighten the loose screws or bolts. Be careful not to overtighten, as this can crack the plastic housing.
- Replace the Mirror Housing (if damaged): If the mirror housing is cracked or damaged, it may need to be replaced altogether.
Tip: Always double-check that the mirror is securely fastened before driving.
5. Frozen Side Mirrors
In cold weather, side mirrors can freeze and become difficult to adjust. Forcing them could cause damage to the adjustment mechanism.

How to Deal with Frozen Mirrors:
- Use De-icer Spray: Apply a de-icing spray to the mirror and the joints where it attaches to the car. This should thaw the ice without damaging the mechanism.
- Manual Thawing: If a spray isn’t available, use a cloth soaked in warm (not hot) water and apply it to the mirror. Avoid using sharp tools to scrape the ice off, as this can scratch the surface.
- Prevent Future Freezing: Consider investing in heated mirrors if you live in a cold climate, or apply a mirror cover when parking outdoors during winter.
Tip: Always keep de-icer spray in your car during the winter months.
6. Blurred or Cloudy Mirrors
Cloudy or blurred side mirrors can make it difficult to see, especially during rainy or foggy weather. This problem is usually caused by water droplets, dirt, or worn-out reflective coatings.

How to Clean and Restore Clarity:
- Clean the Mirror Surface: Use a microfiber cloth and a glass cleaner to remove any dirt or debris from the mirror.
- Apply Anti-Fog Coating: To prevent future blurring, apply an anti-fog solution specifically designed for car mirrors.
- Replace the Mirror (if needed): If the mirror’s reflective coating is worn out, you may need to replace the mirror glass.
Tip: Regularly cleaning your side mirrors can prevent cloudiness and improve visibility in bad weather.
7. Complete Side Mirror Replacement
In cases where the entire side mirror is damaged beyond repair, such as after a collision, you will need to replace the entire mirror assembly.

How to Replace the Entire Side Mirror:
- Buy the Correct Replacement: Ensure you purchase a side mirror compatible with your vehicle make and model.
- Remove the Damaged Mirror: Use a screwdriver to remove the screws or bolts holding the mirror in place. Carefully detach the wiring (for electric mirrors).
- Install the New Mirror: Attach the new side mirror by connecting the wiring and securing the screws or bolts. Make sure everything is tightly fastened.
Tip: If you’re unsure about installing a new mirror, a mechanic can perform the replacement for a relatively low cost.
Conclusion
Knowing how to fix common side mirror issues can save you from costly repairs and improve your driving safety. From simple alignment fixes to more complex electrical problems, tackling these issues at home is possible with the right tools and knowledge. Regular maintenance and care will ensure your side mirrors remain functional and reliable for years to come. Safe driving starts with clear visibility, so don’t overlook the importance of keeping your car’s side mirrors in top condition.
