Three buttons you MUST press to defog your windows fast – as millions brace for ANOTHER day of sub-zero temps & snow

THE three buttons that drivers must press to defog their windows have been revealed as millions continue to brace for sub-zero temperatures.

Following the nation being hit by amber weather warnings and some continuing to face snow, vehicle owners will want to make sure to listen to the expert advice.

Motorists have been advised to press three dashboard buttons in a specific order to ensure their windscreen clears as quickly as possible.

A car expert who offers advice to those wanting to learn about driving skills and make their strip safer posted the advice on YouTube.

According to Tonggeshuoche it only takes three easy steps to ensure your windscreen defrosts thoroughly.

The first thing drivers will need to do is press the A/C button, setting it to full power.

This should then be followed by pressing the defogging button which can usually be recognised by the wavy lines inside a windscreen symbol.

Most importantly, the air circulation button needs to be turned off.

By deactivating this one, drivers can ensure their car pulls fresh air in from the outside.

Many took to the comments section to respond to the footage.

One user wrote: "For one you don't need to put the AC on when you use the defroster it does the same thing, for two you can't recirculate the car here when you have the defroster on. You didn't even press the button in the video, because you know that."

Another asked: "So in winter while driving do I have to put ac on. Because been cold driver keep car warm?"

With someone else responding: "Yes I do this. But what about when it’s cold and I don’t want the AC on?"

A fourth put: "People who are looking for outside fog solution just use the blower without AC."

Someone else said: "Our windshield is very proned to fogging which is very dangerous."

It comes as travellers faced major disruption earlier today after the nation was hit by heavy snowfall.

Traffic was particularly affected on the M6 and M25 after incidents in the early hours of Monday morning.

While others were impacted by flight delays as runways were forced to close.
