Driver Window Does Not Operate (All Other Windows Operate)

WARNING: This page is about a different car, the 1997 Mercury Mountaineer and 1997 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: This test is associated with DTCs B1398, B1400, B1402, B1403, B1404, B1405, B1408, B1410 and B1342.
  1. Turn ignition switch to OFF position. Connect NGS tester to Data Link Connector (DLC) located below instrument panel under steering column. Using NGS tester, read IGN_GEM PID while rotating ignition switch through START, RUN, OFF and ACC positions. If PID values agree with ignition switch positions, go to next step. If PID values do not agree with ignition switch positions, go to IGNITION STATE CHECK test.
  2. Following manufacturer's instructions, retrieve continuous DTCs from GEM. Using NGS tester, perform ON-DEMAND self-test. If no DTCs are present, go to next step. If DTCs B1402 (continuous and self-test), B1403 (continuous and self-test), B1404 (continuous), B1405 (self-test), B1408 (self-test) and B1410 (continuous and self-test) are present, go to step 9). If DTCs B1398 (continuous and self-test) and B1400 (continuous and self-test) are present, go to next step. If DTC B1342 is present, replace GEM. Clear DTCs and retest.
  3. Turn ignition switch to RUN position. Using NGS tester, access ACTIVE COMMAND MODES. Set active command ACCY RLY on. Read D_PWRLY PID. Toggle active command ONE TOUCH on and off. If D_PWRLY PID value agrees with command mode, go to step 9). If NGS tester indicates OFFO-G, go to next step. If NGS tester indicates ON-B-, go to step 7).
  4. Turn ignition switch to OFF position. Check one-touch down relay. See BATTERY SAVER & ONE-TOUCH DOWN RELAY  under COMPONENT TESTING. If one-touch down relay is okay, go to next step. If one-touch down relay does not test as specified, replace one-touch down relay. Clear DTCs and retest system.
  5. Remove accessory delay relay from relay module located behind center of instrument panel. Measure resistance in Light Blue/Black wire between accessory delay relay socket and one-touch down relay socket. If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms, repair open Light Blue/Black wire. Clear DTCs and retest system.
  6. Disconnect 18-pin GEM connector. Measure resistance in Yellow/Red wire between one-touch down relay socket and 18-pin GEM connector. If resistance is less than 5 ohms, replace GEM. If resistance is greater than 5 ohms, repair open Yellow/Red wire. Clear DTCs and retest system.
  7. Turn ignition switch to OFF position. Check one-touch down relay. See BATTERY SAVER & ONE-TOUCH DOWN RELAY  under COMPONENT TESTING. If one-touch down relay is okay, go to next step. If one-touch down relay does not test as specified, replace one-touch down relay. Clear DTCs and retest system.
  8. Disconnect 18-pin GEM connector. Turn ignition switch to RUN position. Measure voltage at one-touch down relay socket Yellow/Red wire. If voltage is present, repair short to voltage in Yellow/Red wire. If voltage is not present, replace GEM. Clear DTCs and retest system.
  9. Using NGS tester, read D_PW_SW PID while pressing master window switch in UP and DOWN positions. If D_PW_SW PID values agree with master switch positions, go to step 17). If D_PW_SW PID values do not agree with master switch positions, go to next step. If NGS tester indicates SHORT, go to step 15).
  10. Turn ignition switch to OFF position. Remove and disconnect master window switch connector. See POWER WINDOW SWITCH  under REMOVAL & INSTALLATION. Using NGS tester, read D_PW_SW PID. Connect a jumper wire between ground and master window switch connector Red/Yellow wire terminal. Connect another jumper wire between battery voltage and master window switch connector Tan/Light Blue wire terminal. Turn ignition switch to RUN position. If NGS tester does not indicate DOWN, remove jumper wires and go to next step. If NGS tester indicates DOWN, remove jumper wires and go to step 14).
  11. Disconnect 18-pin GEM connector. Measure resistance in Tan/Light Blue wire between 18-pin GEM connector and master window switch connector. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Tan/Light Blue wire. Clear DTCs and retest system.
  12. Measure resistance between ground and Tan/Light Blue wire at 18-pin GEM connector. If resistance is greater than 10 k/ohms, go to next step. If resistance is less than 10 k/ohms, repair short to ground in Tan/Light Blue wire. Clear DTCs and retest system.
  13. Measure resistance in White/Black wire between 18-pin GEM connector and master window switch connector. If resistance is less than 5 ohms, replace GEM. If resistance is greater than 5 ohms, repair open in White/Black wire. Clear DTCs and retest system.
  14. Turn ignition switch to OFF position. Using NGS tester, read D_PW_SW PID. Connect a jumper wire between ground and master window switch connector Tan/Light Blue wire terminal. Connect another jumper wire between battery voltage and master window switch connector White/Black wire terminal. If NGS tester does not indicate UP, repair White/Black wire. If NGS tester indicates UP, replace master window switch. Clear DTCs and retest system.
  15. Turn ignition switch to OFF position. Remove and disconnect master window switch. See POWER WINDOW SWITCH  under REMOVAL & INSTALLATION. Disconnect 18-pin GEM connector. Turn ignition switch to RUN position. Measure voltage at 18-pin GEM connector Tan/Light Blue wire. If voltage is present, repair short to voltage in Tan/Light Blue wire. Clear DTCs and retest system. If voltage is not present, go to next step.
  16. Measure voltage at 18-pin GEM connector White/Black wire. If voltage is present, repair short to voltage in White/Black wire. If voltage is not present, replace GEM. Clear DTCs and retest system.
  17. Turn ignition switch to OFF position. Disconnect left front power window motor connector. See POWER WINDOW MOTOR  under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Measure voltage at power window motor connector Red wire terminal while holding left front power window switch in DOWN position. If voltage is greater than 10 volts, go to step 20). If voltage is less than 10 volts, exit ACTIVE COMMAND MODE and go to next step.
  18. Turn ignition switch to OFF position. Remove one-touch down relay from relay module located behind center of instrument panel. Measure resistance in Red wire between one-touch down relay and left front power window motor. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Red wire.
  19. Remove and disconnect master window switch connector. See POWER WINDOW SWITCH  under REMOVAL & INSTALLATION. Measure resistance in Tan/Light Blue wire between master window switch and one-touch down relay. If resistance is less than 5 ohms, replace one-touch down relay. If resistance is greater than 5 ohms, repair open in Tan/Light Blue wire. Clear DTCs and retest system.
  20. Measure voltage at power window motor connector White/Black wire terminal while holding left front power window switch in UP position. If voltage is greater than 10 volts, replace left front power window motor. If voltage is less than 10 volts, repair open in White/Black wire. Clear DTCs and retest system.
