Can anyone give me any suggestions and/or solutions to the problem/issue I am about to describe? It would be most welcome I am at a loss as to how to resolve my issue!

A few months ago, my truck (2004 Dodge Ram 1500 V8 Hemi) began beeping and making the bell noises while driving.. I looked at my gauges and they ALL dropped down to nothing zero, no reading whatsoever, but the truck was perfectly driveable still I just had no gauges for a bit. Then it would return to normal and be fine again. Then everything would stop working again etc etc. It could go a few hours to a few days between "beepings" it had no patterns. Then as it progressed (all this while driving), I would have no wipers or signals or horn or brake lights etc when everything went down to zero or no reading it just got worse and worse. My mechanic friend, thought for sure 100% that it was my main fusebox in the truck under the hood, after taking my whole dash apart. So I bought a new fusebox, and at first that seemed to fix it, but after a day or two it started up again. The only way to temporaily get my gauges back NOW if this happens while driving, is to put on my emergency brake half way while driving. I know this is bad but I kinda need brake lights if say a cop is behind me etc. Does anyone know what the problem is? Has anyone else experienced this? Does anyone know how to fix this? I am guessing obviously it's electrical, could be a lose connection or ground wire maybe... Please any suggestions are welcome I am at a loss and would really appreciate it. Thanks..

 

Very strange, my first thought was fuse box as well. Some of these trucks have a front control module that handles a lot of stuff similar to this. I am no expert, so look into that and see if your truck has that and what all it controls. Someone with more exp than me will chime in I'm sure. Maybe FCM attached to fuse box? Did you change that too?

 

Also found this: The Front Control Module (FCM) is a micro controller located in the left front corner of the engine compartment. It is necessary to position the Integrated Power Module (IPM) aside in order to access the front control module on this vehicle. The FCM mates to the Power Distribution Center (PDC) to form the IPM. The IPM connects directly to the battery and provides the primary means of circuit protection and power distribution for all vehicle electrical systems. The FCM controls power to some of the vehicle systems electrical and electromechanical loads based on inputs received from hard wired switch inputs and data received on the PCI bus circuit.

I also forgot to mention that during this problem, all the dash lights come on all at once while the gauges are at zero, and it reads no bus where the gauges are as well...
