hello guys how does the dashboard switch work for the front axle when i switch mine to engage i hear air leaking and I'm not sure if its working any when to test it

You need to fix the air leak first and then you can test the front axle by jacking up one front wheel and turn it, you should be able to turn it in the unlock position, then turn the switch to lock position and see if it locks in and does not turn.
