Check the cable that locks the hubs check for vacuum at the servo.

The 4x4 is not vacuum operated and I already replaced the actuator and the fuse is good. Is there a relay to check, if so where would it be? It is not on the firewall and the relays near the fuse panel are not labelled as to what they are for.
Thanks

Check the servo to make sure your receiving a signal at the servo when u shift it to 4wd drive.
