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

Speedometer stopped working after fitting an alarm. What could be the problem?


Put everything back the way it was and see if speedometer starts working again?
Newer instrument clusters, the gages are not hardwired, The cluster receives buss data telling the instrument what to do with gages and speedometer. Checking the speedometer/vss sending unit would be a thought. Hopefully, you didn't hurt the instrument cluster?

The speedometer on my 2004 Pontiac Montana quit working. Is there a fuse for that?


Nope. The speedometer needs a signal from the vehicle speed sensor to operate. Is the check engine light on? If so, scan for any codes that may indicate a VSS problem. If no codes, possible internal cluster issue with the speedometer head

Instrument Cluster Replacement
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Disconnect the negative battery cable. Remove the hazard lamps switch by gently pulling the knob straight up. Remove the instrument cluster bezel from the instrument panel. Refer to Instrument Panel Cluster Trim Plate Bezel Replacement . Remove the 4 screws and pull the instrument cluster assembly forward from the instrument panel.

What is the location of fuse for speedometer on 2o04 ford explorer


Speedometer The instrument cluster receives the vehicle speed sensor (VSS) signal from the powertrain control module (PCM) through the standard corporate protocol (SCP) communication network. The instrument cluster monitors the VSS input from the PCM and commands the speedometer with a corresponding movement of the pointer.
  • The speedometer/odometer is inoperative
  • Circuitry.
  • Powertrain control module (PCM).
  • Instrument cluster.
  • Go To Pinpoint Test L .
PINPOINT TEST L: THE SPEEDOMETER/ODOMETER IS INOPERATIVE Test Step Result / Action to Take L1 RETRIEVE THE RECORDED DTCS FROM BOTH CONTINUOUS AND ON-DEMAND INSTRUMENT CLUSTER SELF-TESTS
  • Use the recorded instrument cluster DTCs from the continuous and on-demand self-tests.
  • Are any instrument cluster DTCs recorded?
Yes
If instrument cluster U1123 is retrieved, REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual to continue diagnosis.

For all other instrument cluster DTCs, REFER to the Instrument Cluster Diagnostic Trouble Code (DTC) Index.

No
For inoperative speedometer, GO to L2 .

For inoperative odometer, GO to L3 . L2 CARRY OUT THE SPEEDOMETER ACTIVE COMMAND USING THE DIAGNOSTIC TOOL
  • Connect the diagnostic tool.
  • Key in ON position.
  • Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Active Command.
  • Select the instrument cluster speedometer active command.
  • Trigger the speedometer and scroll in increments of 10% while monitoring the speedometer. The speedometer should increase in increments of approximately 20 km/h (12 mph) for each 10% change.
  • Does the speedometer increase within specifications?
Yes
REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual to continue diagnosis.

No
GO to L4 . L3 MONITOR THE INTEGRATED CIRCUIT DISPLAYS
  • Key in ON position.
  • Monitor the compass, air temperature and message center functions of the integrated circuit display.
  • Do the compass, air temperature or message center displays operate correctly?
Yes
GO to L4 .

No
Go To Pinpoint Test AE . L4 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
  • Disconnect all instrument cluster connectors.
  • Check for:
    • corrosion
    • pushed-out pins
  • Connect all instrument cluster connectors and make sure they seat correctly.
  • Operate the system and verify the concern is still present.
  • Is the concern still present?
Yes
INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. There isn't a fuse just for the speedometer , there are four fuse for the whole instrument cluster . If one of these fuse's were burnt you would have more then just the speedometer not working ! You need to have a scan tool to find out what is up ! you could need a new cluster ! Is the check engine light on ? if not wouldn't think vehicle speed sensor bad , besides speed info for speedometer PCM uses for transmission shift points ! Good luck ,hope this helps !
