Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Was the front axle actuator ever updated to the full electric actuator or does it have the old style gas charged actuator?

Have you checked to make sure the 4wd fuse is o.k.?

Let me know so we can continue,thanks Pete.

I had to have a mechanic fix it but thanks anyway this takes too long

I apologize for the delay.If there is anything else I can help with here let me know.I know that on this model the update required soldering in a new wire for the new actuator and if the new actuator was already installed the solder can corrode or break free and cause this here.I have also seen the actuator on the front differential fail requiring replacement.

Thanks Pete
