My 4x4 was not working so I checked the fuse box and found that the fuse was blown. I replaced it and tried the 4x4 again and it blew the fuse again. Any ideas what is going on?

Most likely your front diff actuator is shorted causing this fuse to blow. To test you need to unplug the electrical plug at the front differential and activate 4wd, if the fuse does not blow anymore then you have to replace the actuator. This is a common problem. Get back to me if you need further assistance.
