Installation Steps:
- Prepare the Vehicle: Park the vehicle on a level surface and engage the parking brake. Disconnect the negative terminal of the vehicle's battery to prevent electrical hazards.
- Access Mirror Housing: Carefully remove the existing mirror glass from its housing. Refer to your vehicle's service manual for specific instructions on mirror glass removal, as this can vary by vehicle model.
- Install Heating Elements: Adhere the heating elements from the kit to the back of the mirror glass. Ensure the surface is clean and dry before application for optimal adhesion. Position the elements to cover the maximum possible surface area of the mirror.
- Route Wiring: Route the wiring from the heating elements through the mirror housing and into the vehicle's door panel. Ensure wiring is secured and does not interfere with mirror movement or window operation.
- Electrical Connection: Connect the heating element wiring to a suitable power source. This typically involves tapping into an existing heated mirror circuit, a defroster circuit, or installing a new fused circuit with a dedicated switch. Ensure all connections are crimped securely and insulated with heat shrink tubing or electrical tape. The kit is designed for both left and right mirror positions.
- Reassemble Mirror: Carefully reattach the mirror glass to its housing. Reinstall any trim panels removed during the process.
- Reconnect Battery: Reconnect the negative terminal of the vehicle's battery.
- Test Functionality: Turn on the vehicle and activate the heated mirror function (if integrated with the vehicle's defroster) or the dedicated switch. Verify that the mirrors begin to warm up.
Operating Instructions
Once installed, the Velvac 748355 Heated Mirror Kit operates by warming the mirror surface to clear frost, ice, or fog. The activation method depends on how the kit was wired into your vehicle's electrical system:
- Integrated with Vehicle Defroster: If wired to the vehicle's rear window defroster circuit, the heated mirrors will activate automatically when the rear defroster is turned on.
- Dedicated Switch: If a separate switch was installed, activate the heated mirrors by pressing this switch.
- Automatic Activation: Some advanced vehicle systems may allow for automatic activation based on ambient temperature, if wired accordingly.
Allow a few minutes for the heating elements to reach optimal temperature and begin clearing the mirror surface. Turn off the heating function when no longer needed to conserve vehicle power.
Maintenance
The Velvac 748355 Heated Mirror Kit requires minimal maintenance. Regular inspection and cleaning are recommended to ensure optimal performance and longevity.
- Cleaning: Clean the mirror glass regularly with a standard automotive glass cleaner. Avoid abrasive cleaners or tools that could scratch the mirror surface or damage the heating elements.
- Wiring Inspection: Periodically inspect all visible wiring and connections for signs of wear, corrosion, or damage. Ensure connections remain secure.
- Functionality Check: Test the heated mirror function periodically, especially before cold weather seasons, to ensure it activates and heats properly.
