Replace the power window main switch.
No
Go to the next step.
2
•  Does the sensor built inside the power window motor send the pulse signals during operating the power window motor?
•  Is voltage between the terminals of power window mortor connecter (4-pin) and ground approx.6V?
―  Terminal1A (sensor 1 signal).
―  Terminal1C (sensor 2 signal).
Yes
Go to the next step.
No
Replace the power window motor.
3
•  Does the power window main switch receive the pulse signals during operating the power window motor?
•  Is voltage between the terminals of power window main switch connecter (4-pin) and ground approx.6V?
―  Terminal2D (sensor 1 signal).
―  Terminal2B (sensor 2 signal).
Yes
Replace the power window main switch.
No
Inspect open or short circuit in the wiring harness between power window motor (sensor) and power window main switch.Inspect the connection of the power window motor and power window main switch connectors. (such as damaged/pulled-out pins, corrosion).Repair or replace the suspect part if necessary.
