okay guys 4x4 high and low dont work but the auto 4x4 does i can raise it up and engage the 4x4 and the front axle does lock so im not understanding why i dont have 4x4?no codes scanner showing everything is locking turning on.my thoughts are its the module or a ground problem but why would auto 4x4 work?

The problem is usually in the switch on the dash 90% of the time. Your running gear is probably fine, the switch is junk...

i just installed the updated switch yesterday it didnt do anything becides the yellow lights in it being almost imposible to see.

Then maybe it's a wiring problem, if the light is dim it could be a bad ground or common, this is the same power that tells your servos to move, find out what voltage is supposed to be there and unplug at the servo and check for it...

i think the dim lights are in the switch because i took it off and put the original back in and the lights are perfect.im getting the new one replaced tommorow we will see.looking at the wire diagram all motor functions are on the same wire as4x4auto and 4x4 high and low so i cant see it being wiring because 4x4 auto works perfect?im leaning towards the module but i dont have 100% fact its that.
