Why Does the Wiper Move When the Ignition Switch Is Turned On?

[DelWalter]

Turning on the ignition switch causes the wiper to move because a reserved position is designed. The wiper is designed with a reserved position: When the car starts or shuts down, the wiper moves slightly because a reserved position is designed in its travel path. After losing power due to the disappearance of oil pressure, air pressure, or electricity, the wiper returns to its original position. If the wiper was in use before shutting down and it moves slightly, this is normal. During normal operation, the wiper stops at a position approximately 5 cm above its usual resting place. Precautions for observing the wiper: When turning off, the wiper will go through a process of returning to its original position, which is why you see it move slightly. Additionally, if the wiper activates without being turned on, it might be due to a sudden connection at the wiper's joint. In this case, it is recommended to check the power connection point of the front wiper, which is usually located above the washer fluid reservoir.
