Can you check if it's working before pullingit apart?

see if it clicks when you push 4x4 button or unplug both plugs on it and turn the key to run and press the white test button if it flashes its good

Is this white button on the Shift Module? I recently bought 94 Explorer, 4WD buttons don't work (sometimes, Dash Illumination behind the buttons is on; press a button, Dash Illumination goes off, although there is clicking heard from the back). Leads me to believe there is a short somewhere inside the switch (also 4x4/Low Range lights do not illuminate on the dash although the bulbs appear to be fine).

I thought about taking the switch apart, however I figured I'd examine all possibilities before doing so, in case it isn't broken.
