Warning Signs the Black Side/Door Mirror with Turn Signal is Failing
- The turn signal in the mirror doesn't light up.
- The mirror doesn't adjust properly or at all.
- The mirror glass is cracked or broken.
- The mirror housing is damaged.
- The mirror vibrates excessively while driving.
- The mirror folds in or out on its own.
How to Test if This Part is the Problem vs Other Components
- Check the turn signal bulb: If only the turn signal isn't working, start by checking the bulb. A blown bulb is the most common cause.
- Inspect the wiring: Look for any damaged or loose wires connected to the mirror.
- Test the mirror adjustment: Try adjusting the mirror in all directions. If it doesn't move, there may be a problem with the motor or switch.
- Check the fuse: Locate the fuse for the side mirrors and check if it's blown.
- Use a multimeter: If you're comfortable using a multimeter, you can test the voltage and continuity of the wires going to the mirror. If there's no voltage, the problem may be further upstream.
Common Failure Causes for This Part
- Impact damage: Getting hit by another car, hitting an object, or even just a hard bump can damage the mirror.
- Weather exposure: Sun, rain, and snow can cause the plastic and electrical components to deteriorate over time.
- Electrical problems: Short circuits, blown fuses, or faulty wiring can cause the mirror to stop working.
- Motor failure: The motor that adjusts the mirror can wear out over time.
- Corrosion: Rust and corrosion can damage the electrical connections and mechanical parts of the mirror.
