The IC CE300 dash has been a regular problem in cold weather. The dash does not come to life for up to 20 minutes after start-up. Scary as heck not being able to monitor engine during cold weather. The response from IC seems to be try another dash. May or may not be any better.
this topic is almost a month old so i you havent figured it out. i had several buses do this i replaced headlight switch and solved the problem. swap out the head light with same year type to test
I was searching for info on another issue I am having and ran across this thread. I have one bus doing this exact thing. Backlight for heat gauge is on constantly. The light doesn't bother me as much as the gauge isn't reading engine temp either. Ugh!! I would have to look at my records to see but I think this will make the second gauge assy for this bus. Unit has 90k on it. Double UGH!!!
