Heated windshields are made by laying a nearly invisible web of extremely fine tungsten wires within the windshield glass, so you may not be able to tell visibly if you have a heated windshield. Most typical heated windshields have a heated wiper park, that resembles and works in conjunction with the back glass defrost. The best way to tell is by a looking on the dashboard or console for a button or indicator, or consult your vehicle’s manual.
How does a heated windshield work?
The very thin web of tungsten wire (the same wire used in lightbulbs) layered in the glass are heated up to raise the temperature of the surface of the glass to defrost or melt snow and ice away from the windshield. While the windshield may not get hot or even warm, it will raise the temperature enough to bring the surface to above freezing so that ice, precipitation, and condensation do not build up and increase visibility of the road.
What are the benefits of having a heated windshield?
The main benefits of a heated windshield are clearing away ice and condensation away from the windshield, improving visibility. The added benefit of that is not having to run the heaters or air conditioner to defog the windshield, saving gas and reducing noise levels by eliminating the blowers. This helps you in the long run by paying for gas less often, saving you money.
Heated Windshield and Replacement
If your windshield is damaged enough to need replacing, you will need to tell the technicians doing the replacement that you have a heated windshield, so the right glass can be ordered. Typically, the heated windshield system has wires that lead into your car, and if the windshield is being removed for replacement, those can be disconnected and ready for a new windshield.
