Hey guys i just need some wiring diagrams for my 91 explorer 4wd XLT. what im trying to do is trace the wiring for myauto 4x4 system. My auto 4x4 button does nothing when pushed and the light on the switch doesnt come on at all. ive checked all fuses under dash and in engine compartment and so far ive found nothing. I was hoping if i had a wiring diagram it may show me if there are fusible links in the 4x4 switch wiring that may be bad or somthing maybe to do with a ground.I dont know im just grasping for any ideas or help at this point its strange because when i got the explorer the 4x4 switch worked fine the lights came on the transfer case motor would shift like it was engaging but the tranny didnt work at all. Now i got the tranny and motor both rebuilt and put back in and the dumb 4x4 switch does nothing ,,no lights working and no shifting in the transfer case motor its like completely dead.If anyone can hook me up with some wiring diagrams or insight to what might be going on with my 4x4 system please help me out here!!Id really appreciate it.
