I dunno why no one actually seeks out why this happens. You air cond evaporator valve stuck or clogged. So you definitely need to get it serviced. How to know?

Just notice that your air cond vent is spewing vapour.

And while you park your car, the amount of condensation water left on the floor is a lot more than usual.

And if you drive a car that has interior condensation problem even if the above symptoms are not visible, you water from outside that made way inside of the cabin.

If you no money to service aid cond or lazy, you can choose this method.

Wipe your windows clean with just water or slight detergent water. Dry it. Then use shaving cream. Yes any shaving cream. Brand or price does not matter. Spray on cloth and wipe on screen. Wipe till clear. Now your screen will be vapour resistant for a long time.

This method is the best and cheapest method. Rain X whatever interior anti fog are all overpriced shit. All have the same ingredients to dilute water. Dilute and not repel. Yes see it in action and you will understand. Repel means something like Never wet. Anti fog does not repel water. They absorb and flatten the water droplets so it will not disperse light. If eventually you encounter really high water in air content, then you will see run off like waves on the screen.

Don't belief? Try it on your house mirror. Then use hot water kettle or your mouth to make the water vapour stick to the glass. It will not blur it.

Also do not use on exterior mirror. the run off will be just as worse as fogging.
