Re: speedometerand temp gauge quit
Check fuse panel. Also the temp sensor might be bad on motor. Also check the connection on trans, on pick up sensor of speed. Speed sensor might also be bad???? Check your ground on the motor & firewall. That can be a proble also,

No it's not it works on the can. Controller area network.
suspect battery fault or more likely the instrument cluster is at fault.
do all gauges drop and the speedo reading is just dashes?
if so this is a cluster fault. Sorry!
It may be that the speedo and temp are mechanical, whereas the tach and fuel are electrical. Check fuse for inst. cluster for clean and tight fitment. Check electrical connection at back of inst. cluster.
You should have a fuse in the fusebox for the instrument cluster. The instrument cluster houses your gauges, speedometer, clock, and temperature gauge or light. Check the fuse to see if it blown and replace with the same size number on the fuse. Don't decrease or increase the number of the fuse. Stay with the same amp number that is on the old fuse when you replace it. Hope this helps.Good luck.
Sounds like you need a new car.
With joking aside, the problem with your speedo, tach, gas guage, temp gauge and odometer can probably be one of two things. Check your fuses. If they are fine you may need to replace your cluster panel. I had to have the entire thing changed over my speedo not working right. It was not cheap. You might want to check the relay box under the hood. Does your transmission leak? Check the fuses and relay on it also. Get a new ignition switch and replace the old one if your key is stuck. You can try WD40 on that key but don't expect any miracles. The bearings are likely shot. Sorry I posted all of this bad news. Good luck.
I am no expert on this but have the same problem. Here is where I am at. I bought the truck used, needed a new PCM which after installing one from a gas job and verifying that wiring was good, bought a reman from Chrysler. Speedo still did not work even though it did with the gas PCM but was fluctuating allover. Chrysler replaced PCM and speedo started to work intermittantly. Took truck into dealer and $600. later told mechanic thought it was faulty PCM. He called Chrysler and asked them to pull one from the shelf and test. They said needed a new crankshaft speed sensor.Mechanic took truck on the road, shifted into nuetral then turned ignition back on, speedo works. Replaced crankshaft speed sensor and situation didn't change. Total spent $1000. and no speedo and no overdrive. Speedo started working intermittantly, seemed like depending on transmission temperature. Friend that works on dodge said is instrument cluster. tried another cluster still the same. Replaced ignition switch, thinking that may be the problem. Still the same. Bought a new Neutral starting switch, which I have not replaced as of yet. If I place truck in neutral and start the truck speedometer is activated right away but does not stay. So right now am down to two scenarios. The neutral starting switch or,...... the temp sensor in the oil line. Feeling is it is the neutral starting switch. By the way had already replaced speed sensor in tranny and rear end. Going to replace neutral starting switch, cost is $25. for the part and see what happens. Please keep us posted, as others are having the same problem.
You will also need to swap the speedo cluster. thats where the anti theft module is located. After that you may still need to relearn the key switch.I will look at the wiring diagrams and get back to you on the starter circut in side the vehicle. You may have to change some other things.Talk to ya soon. Dan
