Schematic References: Moveable Window Schematics and Door Control Module Schematics Connector End View Reference: Vehicle Access Connector End Views DEFINITION: This diagnostic is used to diagnose either, an inoperative driver door power window, or, a passenger door power window that is inoperative only from the driver door switch assemble (DDSA). If the inoperative window is inoperative in only the Express Up mode, refer to Power Window Express Up Function Inoperative . This test assumes that all DTCs have been diagnosed.
1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | Go to Diagnostic System Check - Vehicle
2 | Verify that the Power Window Inoperative from Master Switch complaint is present. Does the power window system operate from the driver door switch assembly (DDSA) as described in the Description and Operation? | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 3

1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. With the scan tool, observe the Driver LF Window Switch, Driver RF Window Switch, Driver LR Window Switch, and Driver RR Window Switch parameters in the DDSA data list.
4. Operate each power window switch located on the DDSA.

Did the parameters change from the Idle state to the Up, Down, Express Up, and Express Down states?
