Driver Rear Window Inoperative From Both Switches

Possible Causes are:

  1. Remove the Rear Door Trim Panel. Disconnect the rear window switch connector. Turn ignition on. Using a 12-volt test light connected to ground, check the Driver Rear Window Driver Up and Down circuits. Did the test light illuminate brightly on both circuits? If yes, go to next step. If no, go to step  8 .
  2. Remove the Rear Door Trim Panel. Disconnect the Driver Rear Power Window Switch connector. Turn ignition on. Keep the window area clear as the window should move up and down in this test. Connect a jumper wire from the Window Driver Down terminal in the switch connector to ground. Connect a jumper wire from the Window Driver Up terminal in the switch connector and momentarily connect it to the Rear Window Driver Up terminal in the switch connector. Reverse the Jumper wires to run the motor in the opposite direction. Did the Window Motor operate in both directions? If yes, replace the Rear Window Switch. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  3. Remove the Rear Door Trim Panel. Disconnect the Driver Rear Window Switch connector. Disconnect the Driver Rear Power Window Motor connector. Measure the resistance of the Window Driver Down circuit between the window switch connector and the window motor connector. Is the resistance less than 5 ohms? If yes, go to next step. If no, repair the Window Driver Down wire for an open. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  4. Remove the Rear Door Trim Panel. Disconnect the Driver Rear Window Switch connector. Disconnect the Driver Rear Power Window Motor connector. Measure the resistance of the Window Driver Down circuit to ground. Is the resistance less than 1000 ohms? If yes, repair the Window Driver Down wire for a short to ground. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  5. Disconnect the Driver Rear Window Switch connector. Disconnect the Driver Rear Power Window Motor connector. Measure the resistance of the Window Driver Up circuit between the window switch connector and the window motor connector. Is the resistance less than 5 ohms? If yes, go to next step. If no, repair the Window Driver Up wire for an open. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  6. Disconnect the Driver Rear Window Switch connector. Disconnect the Driver Rear Power Window Motor connector. Measure the resistance of the Window Driver Up circuit to ground. Is the resistance less than 1000 ohms? If yes, repair the Window Driver Up Wire for a short to ground. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  7. If there are no possible causes remaining, replace the Rear Window Motor. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  8. Disconnect the Driver Door Module C1 connector. Disconnect the Driver Rear Window Switch connector. Measure the resistance of the Driver Rear Window Driver Down circuit between the DDM connector and the Window Switch connector. Is the resistance less than 5 ohms? If yes, go to next step. If no, repair the Driver Rear Window Driver Down wire for an open. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  9. Disconnect the Driver Door Module C1 connector. Disconnect the Driver Rear Widow Switch connector. Measure the resistance of the Driver Rear Window Driver Up circuit between the DDM connector and the Window Switch connector. Is the resistance less than 5 ohms? If yes, go to next step. If no, repair the Driver Rear Window Driver Up wire for an open. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  10. Disconnect the Driver Door Module C1 connector. Disconnect the Driver Rear Window Switch connector. Measure the resistance of the Driver Rear Window Driver Up circuit to ground. Is the resistance less than 1000 ohms? If yes, repair the Driver Rear Window Driver Up wire for a short to ground. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  11. Disconnect the Driver Door Module C1 connector. Disconnect the Driver Rear Window Switch connector. Measure the resistance of the Driver Rear Window Driver Down circuit to ground. Is the resistance less than 1000 ohms? If yes, repair the Driver Rear Window Driver Down wire for a short to ground. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  12. If there are no possible causes remaining, replace the Driver Door Module (output open). Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
