DEFINITION: This test assumes that all DTCs have been diagnosed.

This test is to be used to diagnose, either an inoperative driver door window, or a passenger door window that is inoperative only from the driver door.

Did you perform the Door Systems Diagnostic System Check?

Go to Step 2

Go to Diagnostic System Check - Door Systems

Verify that the Power Window Inoperative from Master Switch complaint is present.

Does the power window system operate from the master switch as described in the Description and Operation?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

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 Sw, Driver RF Window Sw, Driver RR Window Sw, and Driver LR Window Sw parameters in the Driver Door Module Inputs list.
4. Activate each power window switch on the driver door switch assembly.

Did the parameters change from the Idle to the Up, Down, and for the front door windows, Express Down states?

Go to Step 4

Go to Step 12

Is the inoperative window the driver door window?

Go to Step 5

Go to Power Window Inoperative - Passenger Door

1. Turn the ignition OFF.
2. Disconnect the driver door module (DDM) C3 harness connector.
3. Turn ON the ignition, with the engine OFF.
4. Connect a test lamp between the battery positive voltage circuit and the ground circuit of the connector.

Does the test lamp illuminate?

Go to Step 6

Go to Step 11

1. Connect the driver door module C3 harness connector.
2. Disconnect the harness connector from the driver door power window motor.
3. Connect a test lamp between the power window motor Left Front Up circuit of the harness connector and a good ground.
4. Activate the LH Front Window switch on the driver door switch assembly to the Up position.

Does the test lamp illuminate?

Go to Step 7

Go to Step 9

1. Connect a test lamp between the power window motor Left Front Down circuit of the harness connector and a good ground.
2. Activate the LH Front Window switch on the driver door switch assembly to the Down position.

Does the test lamp illuminate?

Go to Step 8

Go to Step 10

1. Connect a test lamp between the power window motor Left Front Up circuit and the power window motor Left Front Down circuit of the harness connector.
2. Activate the LH Front Window switch on the driver door switch assembly to the Up and Down positions.

Does the test lamp illuminate in both the Up and Down positions?

Go to Step 13

Go to Step 14

Test the power window motor Left Front Up circuit for a short to ground, a high resistance, or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 14

Test the power window motor Left Front Down circuit for a short to ground, a high resistance, or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 14

Test the driver door module battery positive voltage circuit for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 15

Inspect for poor connections at the driver door switch assembly (DDSA) harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 16

Inspect for poor connections at the driver door power window motor harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 17

Inspect for poor connections at the DDM harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 18

Repair the open ground circuit of the DDM. Refer to Wiring Repairs in Wiring Systems.

Did you complete the repair?

Go to Step 19
