4.2 Installation Steps (General Guide)
Note: Disconnect the vehicle's battery before starting any electrical work.
- Remove Door Panel: Carefully remove the interior door panel to access the mirror mounting bolts and electrical connector. Use trim removal tools to prevent damage.
- Disconnect Wiring: Unplug the electrical connector from the existing mirror.
- Remove Old Mirror: Unscrew the mounting bolts holding the old mirror in place and carefully remove it from the vehicle. Retain any washers from the original hardware if the new mirrors do not include them.
- Install New Mirror: Position the new Sanooer towing mirror onto the door. Secure it with the provided nuts or original hardware. Ensure a snug fit without overtightening.
- Connect Wiring: Plug the new mirror's electrical connector into the vehicle's harness. Ensure all connections are secure.
- Test Functions: Reconnect the vehicle's battery. Test all mirror functions: power adjustment, heating, and turn signals.
- Reinstall Door Panel: Once all functions are verified, carefully reinstall the interior door panel. Ensure all clips and fasteners are properly seated.
Caution: When removing and reinstalling door panels, be mindful of internal components such as lock mechanisms and wiring to avoid damage.
5. Operating Instructions
5.1 Mirror Adjustment
- Power Flat Glass: Use your vehicle's interior mirror control switch to adjust the upper flat glass mirror. This allows for precise positioning of your primary rear view.
- Manual Convex Glass: The lower convex glass mirror is manually adjustable. Gently push on the mirror surface to achieve the desired wide-angle view.
5.2 Heated Function
The heated defrost function activates automatically with your vehicle's rear defrost system or via a dedicated switch, if equipped. This feature helps to quickly clear moisture, frost, or ice from the mirror surfaces, maintaining clear visibility in adverse weather conditions.

5.3 Manual Telescoping
To extend the mirrors for towing, grasp the mirror housing firmly and pull it outwards until it locks into the extended position. To retract, push the mirror housing inwards until it locks into the standard position. This feature provides an expanded field of view necessary for safely maneuvering with a trailer.
5.4 Manual Folding
To fold the mirrors, gently push the mirror housing towards the vehicle body. To return them to the operational position, pull them outwards until they click into place. This is useful for parking in confined spaces or protecting the mirrors from damage.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your towing mirrors.
- Cleaning: Clean mirror surfaces with a soft cloth and automotive glass cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the mirror glass or housing finish.
- Inspection: Periodically check the mirror housing for any signs of damage, loose components, or corrosion. Ensure the telescoping and folding mechanisms operate smoothly.
- Electrical Connections: If experiencing intermittent issues, inspect the electrical connections for corrosion or looseness.
7. Troubleshooting
If you encounter issues with your Sanooer Towing Mirrors, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Power adjustment not working | Loose electrical connection, blown fuse, faulty motor. | Check wiring harness connection. Inspect vehicle's fuse box for a blown mirror fuse. If issues persist, professional diagnosis may be required. |
| Heated function not working | Blown fuse, faulty heating element, issue with vehicle's defrost system. | Check relevant fuses. Ensure vehicle's rear defrost is active. If the problem continues, consult a professional. |
| Turn signal not illuminating | Loose electrical connection, faulty LED, wiring issue. | Verify wiring connections. Check for any visible damage to the LED array. |
| Mirror vibrates excessively while driving | Loose mounting bolts, internal component issue, manufacturing defect. | Ensure mounting bolts are securely tightened. If vibration persists, contact customer support. |
| Difficulty telescoping or folding mirrors | Mechanism stiffness, debris in mechanism. | Apply a silicone-based lubricant to the moving parts. Ensure no debris is obstructing the mechanism. |
| Distorted or unclear view in mirror | Optical quality variation, protective film not removed. | Ensure any protective films have been completely removed. If distortion persists, it may be an inherent characteristic of the mirror's optical design. |
