Windshield Help Guide

There are some common questions that we will need to know the answers to prior to installing your windshield. These do not apply to every car, but it does come up. At Floyd Auto Glass to Go, we want to help equip you with the answers so we can properly and safely install the correct windshield for your vehicle.


Heated Wiper Park Area forester12-wiperdeicer1a

This is one of the harder features to tell if you have. Most cars do not have a button turning this feature on, or off. The Heater Wiper Park Area works in conjunction with your defrost to melt the snow and ice faster to free up your wiper blades. Many customers do not realize they have this feature, they assume their defrost is just doing it’s job.

Sometimes it can be very easy to tell, other times it is almost impossible.


The picture to the right makes it very easy to tell. The snow is melting around the Wiper Park area first.





But, how do you tell if there is no snow? You are looking for the defrost coils, much like your rear window. Many times they will be a bright orange color, as the picture to the left. Car Manufactures are getting better at hiding the Heated Wiper Park area, which makes it harder to tell.



Electrochromatic Mirror

What is an Electrochromatic Mirror?


An electrochromatic mirror is a rearview mirror that darkens automatically at night in response to headlights

Kind of like the eyeglasses your Uncle Fuss wore in the ’80s that turned into sunglasses when he stepped out into daylight, electrochromatic mirrors darken when shined on by the headlights of tailing cars. The mirrors are designed to dim like this only at night.

The electrochromatic technology usually is applied to the inside rearview mirror, where it basically saves you the trouble of flipping the mirror manually if blinded by the light. Beyond this luxury aspect, the mirrors have the added benefit of dimming proportionately to the intensity of light they read, where a manual mirror gives you only the choice of day or night. Not every vehicle gives you an Electrochromatic Mirror option, they just come up with it and that model does not have a manual dimming mirror option
20140320_090911Determining if you have an Electrochromatic Mirror is very simple. Take a look at the picture to the left. You will see a manual dimming switch. If you have that switch, you do not have an electrochromatic mirror.




Rain Sensor

The term “rain-sensing wipers” is commonly used for a system designed to clear the windshield of rain, snow, and debris without driver intervention. The system is programmed to automatically activate and alter the speed and rate of the wiper blades to keep outward visibility unobstructed at all times. A rain-sensing wiper system does not clean the windshield any better than a manual system; it simply monitors outward visibility and automatically activates the wipers.

How do they work?

The technology behind rain-sensing wipers is not complicated. A small area of the front windshield glass (usually located on the outside of the vehicle, opposite the rear-view mirror: See Picture on Right) is monitored by an optical sensor. The sensor is designed to project harmless infrared light at the windshield at an angle and then read the amount of light that is reflected back. A clean windshield will reflect nearly all of the light back, while a wet or dirty windshield will cause the light to scatter. The optical sensor can determine the necessary frequency and speed of the windshield wipers by monitoring the amount of light reflected back into the sensor.

How Do I know if I have a Rain Sensor?


The easiest is if you notice your wiper blades turning on automatically. There is sometimes a switch to turn the Automatic Wiper Blades on when it senses rain, and that switch may be turned off. If you are not sure if your wipers are automatic, you should be able to see the sensor from the outside: (See the picture on the left). It will be a gel pack that senses the water. Newer cars are now trying to hide the gel pack inside the visor frit (the little black dots around your windshield), which makes it harder to see the sensor. As a last result, try throwing water on your windshield with your car running, or check your manual.
