When I turned the car on, the cluster wasnt working, the radio was not working, car wouldnt shift gears, and the windows weren't working either. I turned the car off and the next day everything was working fine (except engine light). This keeps on happening, any idea as to what is going on?

 

As you know intermittents can be a tech's worst nightmare.
Usually , when a component fails it fails. Questionable connections cause most of the problems
If you mean the check engine light, you might consider having a place like Autozone check your vehicle for any codes stored. They don;t charge for this.
Before you buy anything , post the codes here and hopefully we might be able to assist , maybe save you some $$$.

2006 ford f250 super duty xlt. 6.0 v8 diesel.

 

I’d take it in and see if they can communicate with the cluster, if not, it could be a board connection issue, or the cluster is failing.. They can be sent in for repair...

 

Power saver relay in the Instrument Cluster would be my first guess. Circuit Board Medics can repair it.
