I know what button you speak of; it lights blue when you press the button and wake it up, then a red light when you activate the remote to run the jacks or slide. If I understand right, the blue light doesn't light up when you press the 'wake' button. This comes from the control board where the overhead step is. Look under your step and there are several fuses on this board. Check them all. Also, you will see several connections there; one for the power source and several for power to each of the jacks and slide. Each as a fuse. There is also a phone line cord. This is called an RJ11 connection. Check to see it's plugged in. The other end goes to that board with the wake-up button you are pressing. If the cord or connectors are bad, the light won't light.
