Power Windows Completely Inoperative

NOTE: This test is associated with DTCs B1302, B1398, B1404, B1405, B1408, B1410 or B1478.
  1. Check power window fuse (in power distribution box) and replace as necessary. Ensure all connections are clean and tight. Check for loose or damaged wires. If problem is found, repair or replace as necessary and go to next step. If connections and wires are okay, go to next step.
  2. Connect NGS tester to Data Link Connector (DLC), located below instrument at right of steering column. Following manufacturer's instructions, retrieve continuous DTCs. Using the NGS tester, perform the ON-DEMAND SELF-TEST  . If DTCs 1302 (self-test) and B1398 (continuous) are present, go to step 4). If DTCs B1398 (continuous and self-test) and B1304 (self-test) are present, repair short to battery in Light Blue/Red wire between GEM and delayed accessory relay. See WIRING DIAGRAMS  . If DTC B1398 (continuous and self-test) is present, go to step 6).
  3. If DTCs B1398 (continuous and self-test) and B1404 (continuous) are present, repair short to ground in Yellow/Red wire between GEM and one-touch down relay. See WIRING DIAGRAMS  . If fuse was open, replace fuse, clear DTCs and retest. If DTC B1404 (continuous) is present, go to step 13). If DTC B1405 (self-test) is present, go to step 14). If DTC B1408 (self-test) is present, replace window switch. If DTC B1410 (continuous and self-test) is present, go to step 15). If DTC B1478 (continuous) is present, go to step 4). If DTC B1408 (self-test) is present, repair short to battery in Orange/White wire between GEM and left window motor. See WIRING DIAGRAMS  . If no DTCs are present, go to step 17).
  4. Using voltmeter, check for battery voltage on Light Green/Orange wire between battery saver relay and window relay. See WIRING DIAGRAMS  . If battery voltage is present, go to next step. If battery voltage is not present, repair open in Light Green/Orange wire.
  5. Remove power window relay. Measure resistance across relay coil terminals. If relay coil is open, replace relay. If relay coil is not open, repair open in Light Blue/Red wire between delay relay and GEM.
  6. Measure voltage on Black/White wire between window relay and fuse panel. If battery voltage is present, go to next step. If battery voltage is not present, repair open in Black/White wire.
  7. Check Black/White wire between fuse panel and power distribution box for open. Repair Black/White wire if necessary. If Black/White wire is okay, go to next step.
  8. Check for battery voltage at power window fuse in power distribution box. If battery voltage is present, go to next step. If battery voltage is not present, repair open feed wire or power distribution box.
  9. Check Black/White wire between fuse panel and power distribution box for short to ground. Repair wire if necessary. If Black/White wire is okay, go to next step.
  10. Check Black/White wire between fuse panel and window relay for short to ground. Repair wire if necessary. If Black/White wire is okay, go to next step.
  11. Check for open in Light Blue/Black wire between power window relay and power window master switch. Repair Light Blue/Black wire if necessary. If Light Blue/Black wire is okay, go to next step.
  12. Check Light Blue/Black wire between power window relay and power window master switch for short to ground. Repair Light Blue/Black wire if necessary. If Light Blue/Black wire is okay, go to next step.
  13. Disconnect negative battery cable. Check Gray wire between one-touch down relay and Generic Electronic Module (GEM) for open. Repair open Gray wire if necessary. If Gray wire is okay, go to next step.
  14. Check one-touch down relay for shorted closed contacts. Replace relay if necessary. If relay is okay, go to next step.
  15. Check for open in White/Black wire between window motor and GEM. Repair wire if necessary. If White/Black wire is okay, go to next step.
  16. Restore all electrical connections. Using New Generation Star (NGS) tester, access ACTIVE COMMAND MODES. Perform one-touch down feature functional test. Energize one-touch down relay. If window moves down, wiggle all related wiring connectors and retest. If window does not move down, replace window motor.
  17. Disconnect negative battery cable. Check Tan/Light Blue wire between master window switch and one-touch down module or relay. Repair Tan/Light Blue wire if necessary. If Tan/Light Blue wire is okay between master switch and one-touch down module or relay, repair Tan/Light Blue wire between one-touch down relay or module and GEM.
