凱迪拉克的水箱開鍋風扇不轉故障

修理過程：測(ce)水溫傳感器電(dian)(dian)(dian)阻基(ji)本正常(chang)。拔下位(wei)于發(fa)動(dong)機(ji)室(shi)乘客側防火墻上兩個(ge)風(feng)扇繼(ji)電(dian)(dian)(dian)器，測(ce)兩個(ge)繼(ji)電(dian)(dian)(dian)器控(kong)制線圈兩端對地均無電(dian)(dian)(dian)壓。查控(kong)制繼(ji)電(dian)(dian)(dian)器盒內保(bao)險絲，發(fa)現(xian)(xian)17 號10A 保(bao)險絲斷，用萬(wan)用表(biao)測(ce)電(dian)(dian)(dian)阻發(fa)現(xian)(xian)有短路現(xian)(xian)象(xiang)。仔細(xi)檢查發(fa)現(xian)(xian)線束被空調儲液罐(guan)旁(pang)一爪磨破，其中一淡藍(lan)色/黑色線正是控(kong)制風(feng)扇的線。

匯總(zong)：因短路故障(zhang)構成(cheng)燒穩(wen)妥，那樣(yang)干涉現象應確認穩(wen)妥絲燒的根本(ben)原因，不可能換穩(wen)妥絲后都會再燒。
