If i remember right on the 04, its all done electronically going from the speed sensor in your transmission, to the computer, and from there to your speedometer, unfortunetally if it is the cluster the only way to fix it is to replace your gauge cluster, sorry i couldnt be of more help or have better news.

I have a 1998'Ford Explorer and half the dash lights are out and all pod a sudden my speedometer just quit. Need to know what fuses would go to these, so I can try that. Ty


Sorry but it's not a fuse problem . There is not a fuse just for the speedometer . The microprocessor inside the instrument cluster determines where the speedometer needle points , just like the fuel gauge , tachometer etc... Having the vehicle checked for DTC'S would be the proper step to take .
Vehicle Speed Signal
The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-wheel anti-lock brake system (4WABS) module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input.
Speedometer
The electronic speedometer receives a speed signal from the 4WABS module.

  • The Speedometer/Odometer Is Inoperative
  • Circuitry.
  • Speedometer.
  • GO to Pinpoint Test E .

No where in this factory diagnostic step does it say to check a fuse !

PINPOINT TEST E: THE SPEEDOMETER/ODOMETER IS INOPERATIVE CONDITIONS DETAILS/RESULTS/ACTIONS E1 CHECK THE VOLTAGE TO THE INSTRUMENT CLUSTER
Instrument Cluster
Measure the voltage between instrument cluster C288-7, circuit 1001 (WH/YE), and ground.
  • Is the voltage greater than 10 volts?
Yes GO to E2 .

No REPAIR circuit 1001 (WH/YE). TEST the system for normal operation.
E2 CHECK THE INSTRUMENT CLUSTER PRINTED CIRCUIT
Instrument Cluster
NOTE: Measurements must be made to the speedometer gauge pins that are inside the instrument cluster printed circuit clips.
    Measure the resistance between the speedometer pins (which can be seen in the middle of the instrument cluster printed circuit clips) and the corresponding instrument cluster terminal. Refer to the table for the pin and terminal assignments.
    Instrument Cluster Terminal Speedometer Gauge Pin C286-13 C287-1 S C287-2 G C288-7 BATT
    .

  • Are the resistances less than 1 ohm?
Yes GO to E3 .

No INSTALL a new instrument cluster printed circuit. REFER to Instrument Cluster Printed Circuit . TEST the system for normal operation.
Your best bet , take it to a qualified repair shop

Instrument cluster illuminates intermittently on 1990 eldorado


If this is the analog intrument cluster and the entire instrument cluster is intermittently losing illumination, remove the instrument cluster light fuse and replace it with a new fuse. It is remotely possible that the actual fuse holder wires have broken due to age and would need to be soldered back together.
If this is the digital instrument cluster and the entire display is going dead, it could be anything from the wiring harness to the BCM. If it is the digital instrument cluster, I can really only recommend taking it to a reputable shop or Cadillac dealer to service.

1996 Saturn sl2 cluster acting strange mph and temp working then stop working changed battery plus alternator is it a fuse if so please guide me in the right direction for fuse


Maybe a lose connection or corrosion in the circuit somewhere or stepper motor internal to instrument cluster . Stepper motors are what move the needles to the desired position. An GM had step motor problems . No, couldn't be a fuse or the whole instrument cluster would act up. There is one fuse for the entire instrument cluster , located in the I/P fuse box . IGN.1 10amp fuse . Go to http://www.bbbind.com/free_tsb.html free wiring diagrams . Enter vehicle info , make , model an year ,plus engine size . Then under system click on body & acc. Then under subsystem click on instrumentation an check out wiring diagram . Go on you tube an watch videos on basic electrical testing an voltage drop testing . Get a DVOM - digital volt ohm meter an test the circuit . You'll get hundreds of different reasons on here , but best to learn to test for yourself . More then likely you'll need to have your instrument cluster fixed or replaced .

All my gauges work except my speedometer. What is going on?


Check your speedometer cable at both ends and make sure it is on tight. If the speeometer cable is the original cable it might be time to replace it with a new one. The cable will wear out over time and cause your speedometer to stop working when you drive your car. A replacement cable will cost around $15. If your speedometer cable is good and in working order then you will have to have your instrument cluster repaired. Take a trip to your local junk yard and find your vehicle and then remove that instrument cluster and replace your broken unit. This is cheaper then having your original instrument cluster rebuilt at a shop. If your instrument cluster is digital, check the fuse box located underneath the drivers side steering wheel and locate the "instrument cluster" or "speedometer" fuse. Pull it out and replace it with the same number fuse. To remove your instrument cluster, remove the four phillips screws holding your plastic bezel that surrounds the cluster and then remove the four phillips screws that hold the instrument cluster in place. Now pull it away from the dash and disconnect the electrical plugs. This is very easy to do at home using a phillips screwdriver. If you have any more question, feel free to contact me.

Abs light, brake light, engine light stay on but do not flash


Well, that sucks, for sure. The only commonality I can see between the engine, abs, brake light and speedometer is possibly a bad vehicle speed sensor. But when you throw in the codes for lost comm and cluster error, that muddied the water a bit. I am sure that there are separate fuses for the trailer wiring harness (my 04 chevy has separate fuses, surely an 09 dodge does) so I doubt trailer wiring could have done all this. A lost comm could be caused by a blown fuse. I would inspect every single fuse I could find in the entire vehicle, also, I have researched your problem a bit and have found a couple possible fixes. One is that the abs sensor on the rear differential is known to be sketchy and needs to be changed. The other is cleaning any ground cables that are connected to the fuse box on the front left fender. I hope this helps!

2003 GMC Yukon XL All gauges on instrument panel stopped working. They all stopped at 0, including spedometer, rpms, fuel, oil, etc. The electrical odometer is still working. Is this a fuse problem or does...


If this is an intermittent problem,
remove the IPC 10A fuse in the fuse box under the hood,
not in the fuse panel by the driver side door,
for 5 minutes.
The electronics will reset.
