车 型 :海马M3
发动机:HMAGN15-VF
变速箱:手动变速箱
故障现象
客户反映,车子玻璃升降不正常。技师检查发现,开小灯,右前玻璃下降。
故障分析
开小灯,玻璃升降器,这是不同的两个系统,现在出现关联的故障,说明系统有连电的情况,或者玻璃开关有问题。
维修过程
先更换右前门玻璃升降开关,故障依旧。
使用万用表,检测开关插头,发现开小灯有2根线12伏的电。浅绿黑色线,浅绿线都有。这种情况不正常。
读取线路图,浅绿线是右前门的玻璃下降控制线。此线开小灯有电,说明线路有连电的情况。
先检查车内线路插头,没有发现疑点,检查门子线束,发现密封胶套有问题,发现插头内部有水。
处理方案
利用压缩空气吹干插头,然后安装好插头,密封胶套。试车,故障排除。
维修总结
维修线路连电故障。一般是线路绝缘破坏连电,也有这种进水连电的情况。其次在本例中,在门子线束的插头处容易进水,遇到此类故障,建议先检查这个部位。
