power relay module

I have a 2005 chrysler crossfire, sometimes it won't start. I took it to the dealership and this is the response I received from them: "The problem is the power relay module shorting out killing power to body control module and electronic control module"

I called around trying to find the part that I need so that I can prehaps have my brother to replace it. No one seem to know that part I need, I even called another chrysler dealership.

Any idea what they are stating that I need?

Thank you so much!!!
