my Skoda Octavia's mirrors won't adjust, what could be the issue

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical shock.
• Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Check and Replace Fuse

• Locate the fuse box and find the fuse associated with the mirror adjustment.
• Remove the fuse using a fuse puller.
• Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.
• Reinstall the fuse in the fuse box.

3. Inspect and Replace the Mirror Adjustment Switch

• Remove the switch panel from the door trim using a trim removal tool.
• Disconnect the wiring harness from the switch.
• Test the switch with a multimeter for continuity; replace if defective.
• Reconnect the new switch and reinstall the panel.

4. Inspect Wiring and Connectors

• Remove the door panel to access wiring and connectors.
• Visually inspect for any signs of wear, damage, or corrosion.
• Repair any damaged wiring or connectors as needed.

5. Test Mirror Adjustment Motors

• Disconnect the mirror assembly from the door.
• Using jumper wires, apply direct power from a battery to the mirror motor terminals.
• If the motor operates, it may need reinstallation; if not, it should be replaced.
