How did it get into the car on rainy days?

It may be that the drain hole under the window guard is blocked, or the air inlet of the car is blocked.

There are many places on the car body that basically have water guide grooves or drainage holes, such as doors, front windshields, skylights, trunk lids and other places that basically have drainage holes and water guide grooves.

If the drain hole is blocked, rain water will enter the car during heavy rain, which may damage the electronic equipment on the car.

Precautions:

1. Usually, people who send small cards often see them stuffed into the cracks in the door glass. When friends see them, they must take out the cards first and then raise the glass, otherwise the cards will easily fall into the door when raising the glass. If the card falls into the door, it may block the drain hole of the door, which will affect the serious fault problem.

2. There are basically drainage holes under the door. When it rains heavily, some rainwater will enter the door along the gap between the window glass and the door. If the drain hole is blocked, rainwater will be in the door and damage some electronic equipment of the door.
