My Power Commander will not adjust using the Low, Med, High buttons. The range light on the left is on at 2 "dashes" from the bottom but won't change at all. Is it blown, not connecting right or something else? I really don't know the unit, just had it installed a few years back and was looking at it.
I haven't touched the unit after is was installed 3 years ago so surely don't know how to use it but shouldn't it respond to button presses?
I was trying to do this:

Thanks for any help!
