Symptoms & Diagnosis

Warning signs your Black Power Side/Door Mirror is failing:

  • Mirror Doesn't Adjust: The mirror won't move when you use the power controls.
  • Cracked or Broken Mirror: The glass is damaged, making it hard to see.
  • Loose or Wobbly Mirror: The mirror shakes or moves too easily.
  • Housing Damage: The plastic casing is cracked or broken.
  • Power Issues: The mirror motor makes noise but doesn't move, or there's no power at all.
  • Dim or Non-Functional Turn Signal (if equipped): The turn signal on the mirror doesn't light up or is very dim.

How to test if this part is the problem:

  1. Check the Fuse: Look in your owner's manual to find the fuse for the side mirrors. If it's blown, replace it and see if the mirror works.
  2. Listen for Motor Noise: When you try to adjust the mirror, listen closely. If you hear the motor running but the mirror doesn't move, the motor or gears inside the mirror might be broken.
  3. Inspect the Wiring: Check the wires going to the mirror. Look for any damage, like cuts or frayed wires.
  4. Test the Switch: Use a multimeter to test the power switch that controls the mirrors. If the switch isn't sending power, it could be the problem.
  5. Swap Mirrors (if possible): If you have a working mirror on the other side, you can try swapping them to see if the problem follows the mirror. This can help you figure out if the mirror itself is the issue.

Common failure causes:

  • Impact Damage: Getting hit by another car, hitting an object, or even just a hard bump can damage the mirror.
  • Wear and Tear: Over time, the motor and gears inside the mirror can wear out.
  • Water Damage: Water can get inside the mirror and damage the motor or electrical components.
  • Electrical Problems: Problems with the wiring or the power switch can cause the mirror to stop working.
  • Corrosion: Rust and corrosion can build up on the electrical connections, causing them to fail.

Buyer's Checklist

What to look for when buying this part:

  • Correct Side: Make sure you're buying the right (passenger) side mirror.
  • Power Function: Verify that the mirror has power adjustment if your original mirror had that feature.
  • Turn Signal (if applicable): If your original mirror had a turn signal, make sure the replacement has one too.
  • Color: Check that the color of the mirror housing matches your vehicle's paint. Black is common, but there may be variations.
  • Condition: Inspect the mirror for any damage, like cracks or scratches.
