Test 6: Left Front Window Inoperative

  1. If power window system check was performed, go to next step. If power window system check was not performed, perform system check. See SYSTEM CHECK  under TROUBLE SHOOTING.
  2. Disconnect left front window regulator motor connector. Using DVOM connected to ground, measure voltage at left front window regulator motor connector terminal No. 1 (Red wire). If battery voltage exists, go to step  4 . If battery voltage does not exist, go to next step.
  3. Repair open or high resistance in Red wire between left front window regulator motor and splice S271. See WIRING DIAGRAMS  . After repair is complete, go to step  13 .
  4. Using DVOM connected to ground, measure resistance of Black wire at left front window regulator motor connector terminal No. 4. If resistance is less than 5 ohms, go to step  6 . If resistance is 5 ohms or more, go to next step.
  5. Repair open or high resistance in Black wire between left front window regulator motor connector terminal No. 4 and splice S502. See WIRING DIAGRAMS  . After repair is complete, go to step  13 .
  6. Turn ignition switch to RUN position. Press left front window switch to UP position. Using DVOM connected to ground, measure voltage at left front window regulator motor connector terminal No. 2 (Gray/Green wire). If battery voltage exists, go to step  8 . If battery voltage does not exist, go to next step.
  7. Check for open or high resistance in Gray/Green wire between left front window switch and left front window regulator motor connector terminal No. 2. See WIRING DIAGRAMS  . Repair as necessary. If Gray/Green wire okay, replace left front window switch. See WINDOW SWITCH  under REMOVAL & INSTALLATION. After repair is complete, go to step  13 .
  8. Press left front window switch to DOWN position. Using DVOM connected to ground, measure voltage at left front window regulator motor connector terminal No. 3 (Blue/Red wire). If battery voltage exists, go to step  10 . If battery voltage does not exist, go to next step.
  9. Repair open or high resistance in Blue/Red wire between left front window switch and left front window regulator motor connector terminal No. 3. See WIRING DIAGRAMS  . After repair is complete, go to step  13 .
  10. Using DVOM connected to ground, measure voltage at left front window regulator motor connector terminal No. 5 (Brown/Yellow wire). If battery voltage exists, go to next step. If battery voltage does not exist, go to step  12 .
  11. Replace left front window regulator motor. See WINDOW REGULATOR & MOTOR  under REMOVAL & INSTALLATION. After repair is complete, go to step  13 .
  12. Check for open or high resistance in Brown/Yellow wire between connector C500 and left front window regulator motor connector terminal No. 5. See WIRING DIAGRAMS  . Repair as necessary. If Brown/Yellow wire is okay, check Yellow wire between connector C500 and splice S313 for an open or high resistance. Repair as necessary. After repair is complete, go to next step.
  13. Connect all connectors and components that were disconnected. Verify left front window operates properly. If left front window does not operate properly, go to step  1 .
