I have the switch to change from sport to normal.

how do I no it is working? i cant tell the difference in the 2 driving down the road.

how much are new replacement parts for this thing to keep the adjustable option?

If you don't notice a difference while driving between the two settings, it's not working. Check your voltage while you press the button, it should twitch downward slightly. Otherwise, remove the actuators at the tops of the struts and see if they move when you switch between settings. More than likely the actuators will work so your struts are the culprit. They are pretty darn costly to replace with OEM AAS parts. Most everyone goes aftermarket with adjustable or non-adjustable upgrades. I'm in the process myself.
