Hi! There everyone. I have 89 750il. The head light (low bean ) some time will work and some time will not. When I tap the fuse box the light will come on, and some time need bigger tap on the fuse box to get the head light to come on. Is this cause by the LKM or other ? I have removed the LKM and got it apart. It has two parts in the box and junction by the ribons(4pieces), If my LKM need the fix wich part is the corrected one ?
