 Left front glass lift motor not working左前玻璃升降电机不工作

①General inspection一般检查
1. Power status "OFF".电源状态“OFF”。
2. Connect the diagnostic tool.连接诊断仪。
3. Power status "ON".电源状态“ON”。
4. Use a diagnostic tool to read the fault code and check whether there is a fault.用诊断仪读取故障码，检查是否存在故障。
Check if there is a fault code?检查是否存在故障码？
Yes → Troubleshoot related faults according to the fault code.是>>根据故障码排除相关故障。
No → Go to step 2.否>>去步骤2。
②Check the wiring harness connector检查线束接插件
1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。
2. Check the left front door control module wiring harness for damage, breakage, etc.检查左前门控制模块线束是否存在损坏、断裂等现象。
3. Check the left front door control module harness connector for loose connection or damage.检查左前门控制模块线束接插件是否存在虚接、损坏等现象。
Are the test results normal?检查结果是否正常？
Yes → Go to step 3.是>>去步骤3。
No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。
③Check the left front glass lift motor control wiring harness检查左前玻璃升降电机控制线束
Graphic
1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。
2. Disconnect the left front glass lift motor harness connector FL11 and the left front door control module harness connector FL17.断开左前玻璃升降电机线束接插件FL11与左前门控制模块线束接插件FL17。
3. Use a digital multimeter to measure the resistance between pin 1/2 of FL11 and pin 13/11 of FL17.用数字万用表测量FL11的1/2号针脚与FL17的13/11号针脚之间的电阻。
Standard resistance value: <1标准电阻值：＜1 Ω
Are the test results normal?检查结果是否正常？
Yes → Go to step 4.是>>去步骤4。
No → Repair or replace the left front glass lift motor control harness.否>>维修或更换左前玻璃升降电机控制线束。
④Check the left front window control signal wiring harness检查左前车窗控制信号线束
Graphic
1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。
2. Disconnect the left front door centralized control switch harness connector FL12 and the left front door control module harness connector FL16.断开左前门集控开关线束接插件FL12与左前门控制模块线束接插件FL16。
3. Use a digital multimeter to measure the resistance between pin 4 of FL12 and pin 5 of FL16.用数字万用表测量FL12的4号针脚与FL16的5号针脚之间的电阻。
Standard resistance value: <1标准电阻值：＜1 Ω
Are the test results normal?检查结果是否正常？
Yes → Go to step 5.是>>去步骤5。
No → Repair or replace the left front window control signal harness.否>>维修或更换左前车窗控制信号线束。
⑤Replace the left front glass lift motor更换左前玻璃升降电机
1. Replace the left front glass lift motor and check whether the fault is eliminated.更换左前玻璃升降电机，检查故障是否排除。
Are the test results normal?检查结果是否正常？
Yes → Fault resolved.是>>故障排除。
No → Go to step 6.否>>去步骤6。
⑥Replace the left front door centralized control switch更换左前门集控开关
1. Replace the left front door centralized control switch and check whether the fault is eliminated.更换左前门集控开关，检查故障是否排除。
Are the test results normal?检查结果是否正常？
Yes → Fault resolved.是>>故障排除。
No → Go to step 7.否>>去步骤7。
⑦Replace left front door control module更换左前门控制模块
1. Replace the left front door control module and check whether the fault is eliminated.更换左前门控制模块，检查故障是否排除。
Are the test results normal?检查结果是否正常？
Yes → Fault resolved.是>>故障排除。
No → Find the cause from other fault symptoms.否>>从其他故障现象查找原因。
  Caution:注意：
♦  After replacing the left front door control module, you need to use a diagnostic tool to recalibrate the left front door control module.更换左前门控制模块后，需用诊断仪对左前门控制模块重新标定。
