POWER WINDOW MAIN SWITCH INSPECTION
id091200802000
Vehicles With Exterior Open/close Function
1. Measure the voltage at each terminal (except terminals K and M).
2. Connect the negative battery cable.
3. Inspect the power window main switch connector for continuity at terminals K and M.
4. If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction,replace the power window main switch.
