: How do you diagnose if an IPC (Instrument Panel Cluster) is good or bad?

Hi Cadillac friends,

I have an IPC that seems to be on its last legs. The dashboard dies and then goes back to life intermittently. It has already been diagnosed by a mechanic as being bad, and he was able to show how the IPC cluster could temporarily be brought back to life by squirting it with compressed air. I heard that this is an old trick that electronics technicians use when capacitors are going bad and this may be used as a kind of diagnostic tool to pin-point them.

Are there any other semi-simple diagnostic procedure to tell what's wrong with my IPC? If I get another IPC from the junkyard, can I do some type of diagnosis to tell me if the replacement is any good?

thanks.
