When a power window stops working, the wiring diagram allows you to systematically test each part of the circuit. You can follow the flow of power, checking for voltage at each connection point. For instance, you might start by checking the fuse, then move to the switch, and finally to the motor. This methodical approach, guided by the diagram, ensures you don't miss any potential issues. It’s a step-by-step process for diagnosis:
