Can Rearview Mirror Heating Be Installed Aftermarket?

[Ulysses]

Rearview mirror heating can be installed aftermarket. It involves installing an electric heating element (heating film) inside the mirror lenses on both sides and addressing the wiring method. It is recommended not to attempt this modification yourself, as it may interfere with the vehicle's original electrical system, causing complications and potential safety hazards. It is best to leave this task to professionals. Below are alternative methods to remove water fog from rearview mirrors: 1. Install rain deflectors: This is a relatively low-cost method. After installing rearview mirror rain deflectors (also known as rain visors or rain covers), they can block rainwater during rain, reducing the need to frequently stop and wipe the mirrors. This method is relatively convenient, though its effectiveness is limited during heavy rain. 2. Apply water-repellent coating: Applying a water-repellent coating to the rearview mirrors can also help maintain clear visibility. Many commercially available glass water-repellent coatings primarily contain silicone oil, which alters the surface tension of water on the glass, preventing water from adhering to the mirror surface. 3. Use soap or dishwashing liquid: Rub a clean, damp cloth vigorously with soap (or dishwashing liquid), then evenly spread the soap residue from the cloth onto the rearview mirror. Wait for three to four minutes until the soap (or dishwashing liquid) on the outer surface of the mirror dries, then wipe it off with a tissue.
