Hi there, I am Cam. "This fuse blowing is a result of the front axle actuator. The pins in the switch on the transfer case only send power to the thermal actuator on the front axle, causing it to extend and engage the front axle. More often than not, the thermal actuator fails and causes the system to short out when you engage it.25 Amp is the proper fuse, so remove the actuator on the right side of the axle and replace it.
