hey i was wondering why the fuse inside my truck keeps blowing? i have a service 4wd light and no lights to the 4wd switch any ideas on what is blowing the fuse i think its probably the switch itself but wondering what else it might be? tia

Possible the actuator in the t-case or wiring harness as other possible issues.

i pulled my 4wd switch out and put a new fuse in and started the truck the fuse blew does that mean that the switch is good cause its not the one throwing the high voltage to blow the fuse and does anybody have a diagram of the 4wd circuit? or what would another possibility be?

i agree its the actuator in the t-case i had that problem a winter or two ago
