    Digatal Dash Shows Blank

    I have a 1995 cadillac deville with digital dash. My digital dash went blank and I tried replacing the headlight/dimmer switch, which did not help.

    When I hold either the Econ Button or the Defog Button in the dash will display everything as normal, as long as I hold the button in.

    What should I look for next??
    Thanks in advance for any help

    Sounds like a bad cluster to me.

    If there's a problem with the cluster, your computer should display the code related to it. Hold the off and lo buttons down and post the code here.

    I checked the codes and the dash shows no codes, when it gets to the end it shows PCM?

    Does this mean anything ?

    Thanks

    PCM? just means it is done displaying codes and is asking if you want to go into the PCM diagnostic mode.

    When you say there is no display, is it completely blank, or does the speedometer and shift indicater only show?

    BigM is correct, the computer is done searching for faults. If no faults exsist, I would think there may be a bulb problem. There are codes for the cluster, lights and other displays. I will pull out the GM manual and check on this for you this evening. As much as I'd like too, I can't carry that thing around with me ...esspecially at work !

    Re: Digatal Dash Shows Blank

    The entire dash is blank, the only light is in the radio
    I didn't mention that I had a new fuel pump put in the week before this happened, as I didn't think that
    should have any bearing on this ?? Would it ???
    Thanks

    Ok, the IPC controls the dash cluster. The manual suggests to disconnect the IPC from under the dash, which is located behind the rear seat through the trunk. But before you do this, try pulling these three fuses. A5-IPC (Ign) and B5-IPC (Batt) from the rear compartment fuse panel located in the trunk and A3-IGN1 fuse from the engine compartment fuse panel. Any of these fuses blown will cause this problem.

    I replaced all three fuses with new ones, but still no lights
    It will come on sometimes and stay on for while and than go blank again
    Is the IPC unit something that I can replace, or I just need to unplug and reset?
    Thanks

    The IPC can be reset by unplugging it, but I suspect your problem may be worse. Read this thread link, it's petty envolved, not sure I could do this or not.
