Online timer for 96 seconds
You have started the countdown for a second time while the demister works on a windscreen still marked by frost. During these 96 seconds, you can keep the engine running, check the glass from inside and clear any loosened frost with a proper scraper, without setting off before you can see clearly through every section you need.
With another spell following the first, treat each finish as a separate check rather than assuming two runs will complete the job. Frost may lift from the centre before the edges and mirrors are clear, so the pause between countdowns gives you a useful moment to inspect the result and decide whether another run is actually needed.
Beside a frosty car, the demister fan, engine, passing traffic or a closed door can mask the ending sound. Keep the phone somewhere dry and visible, with its volume audible above the fan, and use the screen as a second cue. If you step outside to scrape, avoid leaving it buried in a coat or bag where the alert may be muffled.
Common questions
What could make the second timed spell too short for clearing frost from the windscreen?
A heavier layer of frost, a colder morning or weak airflow may leave patches after the interval ends. Check the whole windscreen and mirrors, then continue only if the glass still limits your view.
What should you do if the windscreen clears before the timed interval finishes?
Stop the countdown and inspect the glass from the driving position. If every area needed for a clear view is free of frost and mist, there is no need to wait for the alert.
