Door glass does not move up and down in automatic mode

POSSIBLE CAUSE

• Power window system in fail-safe function (Power window motor heat protection circuit is operating)
• No power supply to power window main switch
• No power supply to power window sub switch
• Power window main switch malfunction (power window control unit malfunction, auto switch malfunction)
• Power window sub switch malfunction
• Power window motor malfunction (Sensor inside motor malfunction)
• Malfunction in wiring harness between power window motor (sensor) and power window main switch
• Malfunction in wiring harness between power window motor (sensor) and power window sub switch

Diagnostic procedure

STEP

INSPECTION

ACTION

1
• Turn the ignition switch to LOCK position for 3 min.
• Turn the ignition switch to ON position.
• Initialize the power window system.
• Operate the auto open/close function.
• Does the power window operate properly?
Yes
System is normal.
The power window system auto open/close function does not operate temporarily for any of the following reasons:
• The power window switch is operated while the power window motor protection circuit (integrated in power window motor) is operating.
• The power window main switch power supply is cut off by disconnection of the negative battery cable or removing the fuse.
No
Go to the next step.
2
• Turn the ignition switch to ON position.
• Inspect the two-step down operation.
• Does the two-step down function operate properly?
Yes
Replace the power window main switch.
No
Go to the next step.
3
• Does the sensor built into the power window motor send pulse signals while the power window motor is operating?
• Inspect the voltage at the following power window motor terminals:
- Driver's side:
• A (sensor 1 signal)
• B (sensor 2 signal)
- Except driver's side:
• A (sensor 1 signal)
• B (sensor 2 signal)
• Is the voltage approx. 12V?
Yes
Go to the next step.
No
Replace the power window motor.
4
• Does the sensor built into the power window motor send pulse signals while the power window motor is operating?
• Inspect the voltage at the following power window main switch (14-pin connector), sub switch (12-pin connector) terminals:
- Driver's side:
1H (sensor 1 signal)
1J (sensor 2 signal)
- Except driver's side:
• C (sensor 1 signal)
• F (sensor 2 signal)
• Is the voltage approx. 12V?
Yes
Replace the power window main switch.
No
Inspect for an open or short circuit in wiring between the power window motor (sensor) and the power window main switch.
Inspect the connection of the power window motor and power window main switch connectors. (damaged/pulled-out pins, corrosion)
Repair or replace if necessary.
