Schematic Reference: Power Window Schematics and Door Control Module Schematics

DEFINITION: This test is used to diagnose either, an inoperative driver door window, or, a passenger door window that is inoperative only from the driver door. 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 in Vehicle DTC Information

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 LF Window Switch, RF Window Switch, LR Window Switch, and RR Window Switch parameters in the Driver Door Switch Inputs list.
4. Operate each power window switch on the driver door switch assembly (DDSA).

Did the parameters change from the Idle state to the Up, Down, and 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 C1 harness connector of 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 of the harness connector.

Does the test lamp illuminate?

Go to Step 6

Go to Step 11

1. Connect the C1 harness connector of the driver door module.
2. Disconnect the harness connector of the driver door power window motor.
3. Connect a test lamp between the left front up circuit of the harness connector and a good ground.
4. Operate the driver LF window switch to the Up position.

Does the test lamp illuminate?

Go to Step 7

Go to Step 9

1. Connect a test lamp between the left front down circuit of the harness connector and a good ground.
2. Operate the driver LF window switch to the Down position.

Does the test lamp illuminate?

Go to Step 8

Go to Step 10

1. Connect a test lamp between the left front up circuit and the left front down circuit of the harness connector.
2. Operate the driver LF window switch to both 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 left front up circuit for a short to ground, an open, or a high resistance. 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 left front down circuit for a short to ground, an open, or a high resistance. 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 battery positive voltage circuit of the C1 harness connector for an open, or a high resistance. 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 harness connector of the DDSA. 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 harness connector of the driver door power window motor. 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 harness connector of the driver door module (DDM). 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
