Here's the breakdown:
* Older cars: Often, each window *does* have its own motor. This is because the technology was simpler and individual motors were more cost-effective.
* Newer cars: Many modern cars use a single motor and a cable/pulley system to operate all four windows. This is more efficient and saves space.
How to tell:
* Look at the window switches: If there's a separate switch for each window, it's likely each has its own motor.
* Listen to the motor: If you hear a single motor running when operating different windows, it's likely a shared system.
The bottom line: The specific design varies between car models and manufacturers.
