Plymouth Grand Voyager Overhead Console

I have a 1993 Plymouth Grand Voyager with the overhead console that is supposed to show you the temp, DTE, MPG etc… However, it doesn’t work… Someone suggested checking fuses, but there isn’t a fuse for it and all of the fuses check out ok anyhow. Any ides on how to get this working again ? Thanks!

I would start by trying to find a wiring diagram.
