P38A Information switch

Hi Guys, I cannot get my information switch to work so I can see what mileage I have left in the tank also what the old girl is doing to the gallon, I have tried pushing the button but nothing is happening even the top button for setting the speed limit has stopped. Would it be a bad connection or the stalk has packed up,any ideas would be helpful. Thanks.

I'm wondering if you were to unplug it and get a continuuity reading from the buttons when pressed?

May just want unplugging a good clean with contact cleaner and plugging back in, only one way to find out.
