For those folks argueably lucky enough to have the factory digital clock in their center console (you know the one, right next to your dimmer knob) - I finally got mine to work. I decided to remove this eternally black display and take it apart. Wow, what a crummy design. What I found was the two "adjustment" pins on the front are really just small pressure-sensitive buttons (like you'd expect). The problem is they are backed by a single piece of stiff foil that when pressed, makes contact with the PCB. This foil can easily be fatigued causing it not to "bounce back". As a result, the foil just shorts to the board and blanks the display. I fixed mine by removing the "foil" and replacing it with a piece of tin (made from an old soda can - cut to size). By the time you're done cutting this tiny piece, you may have wished you used a beer can - and drank the beer before you started! Tack solder it back to the PCB and VIOLA! A nice bright green - terrifically 80's dated, display. You'll love it. If anybody wants a little more detail, just email me directly...I'll help you as best I can.
