Aftermarket junk!
bad heater core.
The presence of high humidity, and a difference in temperature between the inside and outside.
Windshield repair and replacement can be very simple. If your windshield is cracked or chipped, the store will use a special kind of melted glass or resin to seal up the damage. If the windshield needs to be repaired, then they will use a process to remove it without damaging your car frame and simply switch it with a new one.
moisture in the air condensing on the colder glass another possiblity could be a leaky heater core.
Oh, dude, it's like this - a windshield replacement is when they straight-up swap out your whole windshield for a new one, like giving your car a fresh pair of glasses. On the other hand, a windshield repair is when they try to fix up a small crack or chip, like putting a band-aid on it and hoping for the best. So, like, one's a total makeover, and the other's just a quick fix, ya know?
you will have coolant in your passenger front floorboard and when you turn your heater on your windshield will fog up
Because of the humidity it is giving off when it falls onto your windshield/////the rain cools your windshield causing the humidity in your car to condense on the glass put on defroster and crack window open to clear this quickly
Heated air is coming up the vents on the inside. If it has enough moisture, it will condense on the relatively cooler windshield. The same thing happens when there is warm moist air being circulated inside the car, and the outside air is cold.
because is broken ? Because is cold outside ? Because you don't know how to turn the switch on ?
It depends on whether the night vision goggles are image intensifiers or the type that are sensitive to infra red. Only the infra red type can see warm objects through fog. Image intensifiers will not be able to see through fog at all.
Typical of the heater core leaking. Overheat because of low fluid and pressure. Foggy windshield due to heater core leaking and will smell antifreeze in the car.
when your heater core is shot it will leak on the passenger side of vehicle and your windshield will fog up most of the time
