DEFINITION: A passenger door power window fails to operate from a passenger door power window switch, or, fails to operate from both the passenger door power window switch and the driver door switch assembly (DDSA). If the inoperative window is inoperative in only the Express Up direction, 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 Windows Inoperative - Passenger Door failure is present.

Do the passenger door power windows operate 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 switch, with the engine OFF.
  3. With the scan tool, select the door control module associated with the inoperative power window.
  4. With the scan tool, observe the Window Switch parameter located in the appropriate door control module data list.
  5. Operate the passenger door window switch of the inoperative window to the Up, Down, Express Up and Express Down positions.

Do the window switch parameters change from the Idle state to the Up, Down, Express Up, and Express Down states?
