Left Front Window Motor Circuit Failure
NOTE:
If other codes are retrieved along with this code, service other codes first.
- Check PID
Using New Generation Star (NGS) tester, access D_PWAMP PID from GEM. Press left front power window switch up. If PID indicates no current, go to next step. If PID indicates current, go to step. 6). - Check Resistance To Motor
Disconnect fuse junction panel connector C4. See Figure. Measure resistance between terminals No. 1 and 25 at connector C4 (fuse junction panel side). If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, go to step 4). - Check Fuse Junction Panel
Disconnect connector C1 from fuse junction panel. Measure resistance between fuse junction panel connector C1, terminal No. 2 and connector C4 terminal No. 25. If resistance is less than 5 ohms, replace GEM. If resistance is greater than 5 ohms, replace fuse junction panel. - Check Orange/White Wire
Disconnect left front window motor harness connector. Measure resistance of Orange/White wire between connector C4, terminal No. 25 and left front window motor harness connector. See Figure. If resistance is less than 5 ohms, go to next step. If resistan ce is greater than 5 ohms, repair open Orange/White wire. - Check White/Black Wire
Measure resistance of White/Black wire between fuse junction panel connector C4, terminal No. 1 and left front window motor harness connector. If resistance is less than 5 ohms, replace window motor. If resistance is greater than 5 ohms, repair open White/Black wire. Restore all electrical connections and retest system. - Check Orange/White Wire For Short
Disconnect fuse junction panel connector C4. See Figure. Measure resistance of Orange/White wire between connector C4, terminal No. 25 and ground. If resistance is greater than 10 k/ohms, go to next step. If resistance is less than 10 k/ohms, go to step 8). - Check Motor For Short To Ground
Disconnect left front window motor. Measure resistance of Orange/White wire between connector C4, terminal No. 25 and ground. If resistance is greater than 10 k/ohms, replace window motor. If resistance is less than 10 k/ohms, repair shorted Orange/White wire. - Check Fuse Junction Panel
Ensure fuse junction panel connector C4 is disconnected. Disconnect GEM from fuse junction panel. Measure resistance between fuse junction panel connector C1, terminal No. 2 and ground. If resistance is less than 10 k/ohms, replace fuse junction panel. If resistance is greater than 10 k/ohms, replace GEM. Retest system.
