I don't have any suggestions, but I may have a similar problem. My autocheck
display has gone out in the past, with the backlight still working, and then
after a day or so come back on, working perfectly. I hope this isn't a sign
that the ignition is going bad as well. Is the autocheck display problem a
common one, or just tied to the ignition?
