1. Measure the voltage at each terminal (other than terminals 1F and 2C).
2. Disconnect the negative battery cable.
3. Inspect the power window main switch connector for continuity at terminals 1F and 2C.
4. If the system does not work properly even though the inspection items or related wiring harnesses do not have any malfunction, replace the power window main switch.
