The overhead console in my 2002 Grand Cherokee has gone dead. For a while it would come on sometimes and not others - now nothing. Sunroof switch and console lights still work fine.
I found a self-test using the C/T and Reset buttons, but nothing happened, so I think I may not be getting power. I looked at a wiring diagram which said there are two fused positive power leads. Does anyone know where these run, or where they are fused?
Same problem. I finally solved it by buying a new circuit board with display from a junk yard for $35.00 and replaced it. they let me try it out there before i had to buy it. Works fine now.

My Jeep does the same thing. one thing that I noticed is, when you press hard on the center it comes back on, temporarily. I have checked all the connections and everything seems normal. However, i did notice that one of the plastic mounts where you screw the module do the overhead console, is broken off. don't really see how that could mess it up, but maybe i'm wrong. So far i haven't found anyway to fix it either, so i will probably have to buy one as well.
I don't have a diagram for your vehicle, but why not check power right at the console. Also check headliner to see if it gets damp or wet when it rains or when vehicle is warm inside Any moisture in the console will give you intermittent crazy problems with electronics.
