Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse related to the mirror adjustment (refer to the owner’s manual).
Remove the fuse using a fuse puller, inspect it for continuity, and replace it if blown.
Reconnect the battery after replacement.

3. Inspect Electrical Connections

Remove the rearview mirror by following these steps:
- Use a flathead screwdriver to gently pry off the cover (if applicable).
- Unscrew the mounting bracket using a Torx screwdriver.
Disconnect the electrical connector from the mirror.
Inspect the connector for corrosion or damage. Clean or replace as necessary.
Reconnect the connector and reattach the mirror.

4. Test Mirror Adjustment Mechanism

With the mirror connected, reconnect the battery.
Test the adjustment buttons to see if the mirror responds.
If the mirror still does not adjust, the internal adjustment motor may be faulty and require replacement.

5. Replace Mirror Adjustment Motor (if necessary)

If the adjustment motor is faulty:
- Carefully remove the mirror again.
- Disassemble the mirror housing to access the adjustment motor.
- Disconnect the motor and replace it with a new part.
