Intermittent electrical issue

So I have a 2006 F350 SuperCrew with a 6o diesel. I started having problems with my instrument cluster how about a month ago it completely shuts down. Along with the radio and all window controls. It's a Lariat Edition. Is it an ECM issue?

Nope. It's probably a power issue.

Okay thank you. I'm sure there's a power control module or something that is causing this. Just don't know where to begin

Take a look at your battery ground wire(s) and connections. Make sure you have clean, tight, and solid, corrosion free contacts at battery and termination points. Make sure battery is properly anchored too. Bouncing and shifting while driving can tug on wires momentatily and cause intermittent issues.

Good luck.

Focus on the power and ground feeds specific to the instrument cluster.

IIRC, the Accessory Delay Relay which provides power to the audio and power window systems, resides in the cluster. If the cluster goes "offline" for any reason, so do the subsystems that it provides power to.
