What is the plastic panel under the windshield wiper called?

[VanPhoebe]

It is called the lower windshield trim panel. Below is relevant information about windshield wipers: 1. Front wipers: Front wipers must effectively remove rain, snow, and dirt; operate in high temperatures (up to 80 degrees Celsius) and low temperatures (down to -30 degrees Celsius); resist corrosion from acids, alkalis, salts, and other harmful substances; and have a lifespan of up to 150,000 wiping cycles (for passenger vehicles). Typically, the wiper control knob is located on the combination switch lever, featuring three settings: low speed, high speed, and intermittent. 2. Working principle: The motor on the electric wiper drives the output shaft via a worm gear on the armature shaft, which then drives the output gear through an idler gear and idler shaft. The output arm connected to the wiper linkage is then manipulated by the output shaft. When the motor rotates, the output arm and linkage are driven to move back and forth. A resistor on the control switch is connected to the motor's armature winding to regulate the motor's speed, allowing the driver to adjust the switch as needed to direct current into the motor's input circuit.
