Need help correcting needles on dials

Without testing ,hard to say for sure . Gauge could be going bad or the engine coolant temp sensor , wiring for sensor , PCM/ECM etc..... Knowing where that info originates an how it gets to the instrument cluster gauge is key in diagnosing the problem . Having worked at GM dealer ships an having correct tools an information gives me an edge over most . Most people would just replace parts an hope it fixes it . The first place to start would be to hook up a factory or professional scan tool an check for DTC'S - diagnostic trouble codes in the instrument cluster an the PCM/ECM . View live data inputs from the coolant temp sensor to the PCM?ECM - engine computer ,also see if that same info is getting to the instrument cluster . Most usually , if the problem is happening at the time we can't find the fault .
The Coolant temp sensor is an input to the PCM , the PCM sends this if to the instrument cluster on the serial data network . Don't know if you know what that is ?

Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 100°F (40°C) or below if:
• The ECM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of serial data communications with the BCM.
• The BCM detects a loss of serial data communications with the ECM.

GM did have problems with stepper motors inside instrument clusters 2003 to 2006 . Stepper motors are what control the gauge needles .

Early and mid 2000 GM Trucks have a instrument cluster issue, think the cluster is your problem and the unit will have to be repaired or replaced.

Bad step motor in the instrument cluster that controls the temp gauge . The best way to check it would be with a professional type scan tool that can view sensor data parameters . You first need to know how that gauge gets the info to set the correct temp . There is a coolant temp sensor located in a coolant passage on the engine . This sensor is a input to the PCM - engine computer . The PCM needs this info fuel managment , the PCM also sends this info. to the instrument cluster over the Class 2 data network ! There is a microprocessor inside the I/C that deciphers these message bits an uses the step motor to control the gauge needle ! Aren't computers great ?
How to repair GM Instrument Cluster Speedometer Gauge Stepper
This guy says 03 to 06 , i have seen gauge's on earlier models go out too . You could by a used cluster on eBay or at a automotive salvage yard or junk yard , what ever you know them by . $20 buck's at salvage yard , more on eBay .

You may have a problem with the coolant temperature sending unit and or the fuel level sending unit or an issue with the instrument cluster.

Have you had it plugged into a diagnostic machine (PIWIS). First to read out fault codes and then to monitor live data from ecu to see if its sending rpm, speed, temp and fuel signals from sensors. If all this is been send to instrument cluster then looks like a cluster fault. Do the lights still work and do the rest of the illuminations come on when the lights are switched on?

repeat question

Many speedo dials on many American models seem to suffer an early demise. It usually turns out to be the dial itself which is faulty, so I'd recommend checking and changing this first

You have a major BCM fault, and/or instrument cluster malfunction...
You will need a high end diagnostic scan and a possible reflash done.

no there isnt a way to reset the the instrument cluster back to zero if your talking about how many miles the vehicle has travelled in its lifetime...you will have to remove the dials and reposition them again...either tht or take it to ford and get some proffesional assistance...

Most likely this is the common 03-05 Cavalier instrument cluster problem where the stepper motors on the cluster's circuit board go out. It can be fixed, check this page for more on how to get it taken care of - Cavalier fuel gauge broken
