92 cadillac sedan deville

digital dash display goes blank and displays lower case "d" and
or lower case "c" in the gas remaining window and the climate
control window - service air conditioner light comes on and goes
back off and air conditioner comes on and display returns but will
not function, i.e. "off" switch. All comes back on and is working
for a minute and then starts all over again. it is below zero right
now and has not happened before. Relay problem or something

Could be relay or could be coincidence. Possible instrument panel problem. This is almost impossible to diagnose without seeing. I suggest you take it to an auto electrical shop in your area for proper diagnosis.
Hope this is helpful to ya,

Thanks, have talked to my local mechanic and made an
appointment. Wish I could still work on my own rigs. Too
complicated and I'm too old for most of it anymore.
