With the key inserted in the driver's door key cylinder, turn the key a second time and hold within 10 seconds to operate the windows (clockwise to open, counterclockwise to close). The windows stop moving when the key is released.
By pressing the UNLOCK button of the keyless transmitter a second time and holding, the windows open. The windows stop moving when the UNLOCK button is released. The windows do not close with the LOCK button.
The system is composed of the power window master switch, the power window control unit and the driver's power window motor. The power window motor incorporates a pulser which generates pulses during the motor's operation and sends the pulses to the power window control unit. As soon as the power window control unit detects no pulses from the pulser, the control unit makes the power window motor stop and reverse. This is to prevent pinching your hand or fingers during auto-up operation.

Do the information indicators display EXIST?
YES -Replace the power window master switch.
NO -Go to step 4.
Are all the wire harnesses OK?
YES -Substitute a known-good power window master switch, and recheck. If DTC is gone, the original master switch is faulty; replace it. If the DTC is still indicated, replace the driver's power window motor.
NO -Repair a short to ground or an open in the wire.
Is DTC B1125 or B1126 indicated?
YES -Troubleshoot the DTC B1125 or B1126 (see DTC B1125: DRIVER'S POWER WINDOW MOTOR A PULSE ERROR; DTC B1126: DRIVER'S POWER WINDOW MOTOR B PULSE ERROR ).
NO -Go to step 5.
Is DTC B1140 indicated?
YES -Faulty door multiplex control unit; replace the power window master switch.
NO -The system is recovered at this time.
