my Volkswagen Tiguan's mirrors won't adjust what's the problem

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Replace the Mirror Adjustment Switch

• Remove the switch panel using a trim removal tool.
• Disconnect the wiring harness from the back of the switch.
• Test the switch with a multimeter to check for continuity.
• If defective, replace with a new switch:
  • Connect the new switch to the wiring harness.
  • Reinstall the switch panel.

3. Check and Replace the Fuse

• Locate the fuse box (typically under the dashboard or engine compartment).
• Identify the fuse for the mirror adjustment (refer to the owner’s manual for the exact location).
• Pull the fuse and inspect it for continuity.
• If blown, replace it with a fuse of the same amperage.

4. Inspect and Repair Wiring

• Remove the door panel to access the wiring harness if necessary.
• Visually inspect the wires for fraying, corrosion, or breaks.
• Repair or replace any damaged wiring using solder and heat shrink tubing or appropriate connectors.

5. Test the Mirror Motors

• If the above steps do not resolve the issue, remove the mirror assembly.
• Connect the mirror motor directly to a battery (use jumper wires) to test for functionality.
• If the motor does not work, replace the mirror assembly.
