How to Read a Window Switch Wiring Diagram
Reading a window switch wiring diagram may seem complicated at first, but it is actually quite simple. The diagram will show you the various components of the power window system, such as the switches, motors, and regulators. Each component will be labeled with a number or letter that corresponds to the wiring diagram. You can then follow the lines and arrows to see how each component is connected to the others.
For example, the switch that controls the driver’s side power window may be labeled “SW1” on the wiring diagram. The motor that moves the window up and down may be labeled “M1”. The regulator that keeps the window in place may be labeled “REG1”. The diagram will also show you which wire is connected to each component, so you can check the wires and connections to make sure they are functioning properly.
