1. Power Window Inoperative |
The driver door switch (DDS) and passenger door switch (PDS) control the power window functions through the power window motor up and down control circuits. The door switches monitor the control circuits for fault conditions when up or down operation is requested prior to activating the function and during operation.
• | Battery voltage must be between 9-16 volts. |
• | The ignition switch is in the ON position. |
The DDS or PDS detects a short to ground or short to voltage on a window motor control circuit.
During 5 occurrences of power window motor operation in an ignition cycle, the door switch has detected excessive current flow on a window motor control circuit.
The power window motor operation will not be attempted whenever this condition is present.
Power window motor operation will be disabled for the current ignition cycle.
When the fault is no longer present, the door switch changes the current DTC to a history DTC.
The DTC will be current for the entire ignition cycle. The DTC will be a history DTC the following ignition cycles until the conditions for setting the DTC have been met.
The door switch will clear the history DTC after 50 fault-free ignition cycles, or in response to a scan tool command.
The DTC can be set due to excessive physical resistance in the window regulator assembly. Ensure proper mechanical operation of the regulator assembly prior to replacing electrical components.
