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.

Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle

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?

Go to Step 4

Go to Step 11

Is the inoperative window the driver door window?

Go to Step 5

Go to Power Window Inoperative - Passenger Door

1. Turn OFF the ignition.
2. Disconnect the C1 harness connector at the driver door module (DDM).
3. Turn ON the ignition, with the engine OFF.
4. Connect a test lamp between the battery positive voltage circuit and the ground circuit at the harness connector.

Does the test lamp illuminate?

Go to Step 6

Go to Step 10

1. Connect the C1 harness connector at the DDM.
2. Disconnect the driver door power window motor harness connector.
3. Connect a test lamp between the power window motor left front up control circuit at the harness connector and ground.
4. Operate the DDSA LF Window Switch to the UP position.

Does the test lamp illuminate?

Go to Step 7

Go to Step 8

1. Connect a test lamp between the power window motor left front down control circuit at the harness connector and ground.
2. Operate the DDSA LF Window Switch to the DOWN position.

Does the test lamp illuminate?
