Instrument panel not working

Could be a fuse. Have somebody who knows about cars look at the instrument cluster fuse to see if the wire inside is broken.

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.

if its not a fuse then it could be the entire instrument panel-2003 is bad for that

sounds like ignition barrel to me.

Problem can be one of two things, a bad sending unit in the gas tank or a defective stepper motor in the instrument cluster. All gauges, speedo and tach are driven by stepper motor that have been known to fail. A technician using a scan tool can determine if the tank sending unit is working.

Had same problem with my 2000 dodge stratus 2.4 liter and transmission would not shift out of 1st gear. Solution was ignition fuse under the hood was blown, one side of fuse working, replaced 10 am fuse everything works, tach, speedometer, gas gauge and transmission started back to shifting.

check all wiring and maby youl get it right

Hello, Last year General Motors lost a lawsuit about the instrument panels in 2002 to 2005 trucks. The following website contains all the information about this lawsuit settlement.

This impacts the entire gauge cluster in your vehicle.
I have the same year and model as yours and my speedo is never accurate and the tach always read 6000.
The issue is the metal bearings that the gauge meter movements use. The bearings are getting dry which impedes the meter movement.

4 resistors on the back of cluster bad get them at radio shack.
