In winter, the car didn't turn on the air conditioner. What does it feel like to stop dripping?

1. The air conditioner was not turned on, but there was frost or fog on the windshield before winter, so the windshield blowing mode was turned on and the air conditioner was turned on automatically. So, it may be air conditioning condensate.

2. Check whether the frozen liquid or glass water tank and the connecting part leak due to thermal expansion and cold contraction during driving.
