ok 4x4 was working fine to other day. now when i start the lights come up as normal and then goes off. when i flip the switch to any pos(4x2-4x4) no lights and the transfer case doesnt engage. is there a way to test the motor. i have turned truck on there is no power on any of the wires to the switch or the transfer case motor. do any of the wires has power running to them or is there a way to check the switch? also my fuse 30a in the power distrubution box appears good, any other fuse controling the motor?
