  4. If driver's, left rear and right rear window are operative, go to step  6 . If driver's, left rear and right rear window are inoperative, go to step  9 .
  5. Disconnect passenger front window switch 8-pin harness connector. Window switch is located in passenger door panel. Using a test light connected to ground, probe master window switch harness connector C1 terminal "D" (Dark Blue wire). See Figure . If test light illuminates, go to step  7 . If test light does not illuminate, go to step  16 .
  6. Disconnect inoperative window switch 8-pin harness connector. Turn ignition switch to RUN position. Using test light connected to ground, probe Center Console (CC) fuse block harness connector C2 terminal D9 or E9. See Figure . If test light illuminates, go to next step. If test light does not illuminate, go to step  10 .
  7. Connect test light between master window switch up and down circuits of inoperative window. See WIRING DIAGRAMS  . Operate inoperative window from master window switch. If test light illuminates, go to next step. If test light does not illuminate, go to step  11 .
  8. Connect inoperative window switch. Disconnect inoperative window motor 2-pin harness connector. Connect test light between inoperative window motor harness connector terminals "A" (Brown wire) and "B" (Dark Blue wire). Operate inoperative window switch to up and down positions. If test light illuminates in both positions, go to step  14 . If test light does not illuminate in either positions, go to step  12 .
  9. Check for open in voltage supply circuit to inoperative window. See WIRING DIAGRAMS  . If problem is found, repair as necessary and go to step  20 . If no problem is found, go to step  13 .
  10. Check for open in Dark Blue wire between inoperative window switch harness connector terminal "A" and master window switch harness connector C1 terminal "D". See Figure and Fig 1 . If problem is found, repair as necessary and go to step  20 . If no problem is found, go to step  13 .
  11. Check for open or short to voltage between inoperative window switch and master window switch up and down circuits. See WIRING DIAGRAMS  . If problem is found, repair as necessary and go to step  20 . If no problem is found, go to step  13 .
  12. Check for open between inoperative window motor and inoperative window switch up and down circuits. If problem is found, repair as necessary and go to step  20 . If no problem is found, go to step  15 .
