I can be driving down the road and all of a sudden my gauges will go crazy well not just my gauges it is the entire instrument cluster. the best way i can describe it is it acts just like it does when you turn on the switch and start the vehicle the speed gauge will go to 120, fuel gauge goes to full(i think if not it goes to E),
Do you know anything about electronic's ? Automotive electronic's take more of a beating , hitting bump's , pot holes ,curbs etc. Enough to jar even the best built electronic componets . Chrysler products have had solder joint's crack , causing intermittent connection problems , could be loose fitting electrical connection's etc.... There is a microprocessor with logic programmed into it , inside the instrument cluster , the gauges ,warning light's are all controlled by modules . The gauges get their info from the PCM/ECM - engine computer over what is called a serial data network , are you familiar with these . The PCI data bus is what it is called . NO Communication issues on 2003 Dodge 1500 trucks is best fixed using...
Probably the best thing to do would be to have the whole vehicle scanned for DTC'S - diagnostic trouble code's . Not at a part's store , they can not read codes in the instrument cluster , BCM - body control module etc.
You could probably check power an ground connections for the IPC , Looking at a wiring diagram so you know which wire's to check . Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year,make ,model an engine size . Under system click on body & accessories ,then under subsystem click instrumentation .Click search button ,then the blue link. To find ground location's on the vehicle you real need some kind of factory service info. or repair manual .

I had the same issue with my dodge caravan and after several attempts by the dealer to fix it, it turned out to be a broken wire. They replaced the relay and it would work for a while and then go blank again. Have the wires checked thoroughly.

Definitely the gauge can be changed, provided the float in the fuel tank is OK, i.e. no leaks. This float connects to a potentiometer which records the current flowing thru it and displays it in the gauge. So before replacing the gauge measure the current and match that against the quantity of fuel in the tank...............sodeep

SORRY but you have a very typical dodge problem.dodges are VERY well known for these little and big wiring problems.you can find an electrical expert thats highly recomended or the dealer.if you don't fix it well,my grandads had some small problems fuel hand radio insturment panel would all stop working some times and some times work fine,then one day it burned the whole harness inside truck and under hood then it really cost a pretty penny.hope you get her fixed..

This Seems Indicative Of a Poor Connection AT The CLUSTER Or A Junction Connecter Close to the Cluster. This is Assuming you Have Ruled OUT ALL ABS COMPONENTS, LOOK at These VERY CLOSLY Because of the Small Volts These Wires Carry , the SMALLEST DEFECT WILL Cause this Type of Symptom that you have given. Please try all of the Above, I feel Confedint that athis is where your Problem Is.
