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.
The electronic speedometer receives a speed signal from the 4WABS module.
- The Speedometer/Odometer Is Inoperative
No where in this factory diagnostic step does it say to check a fuse !
PINPOINT TEST E: THE SPEEDOMETER/ODOMETER IS INOPERATIVE
CHECK THE VOLTAGE TO THE INSTRUMENT CLUSTER
Measure the voltage between instrument cluster C288-7, circuit 1001 (WH/YE), and ground.
- Is the voltage greater than 10 volts?
GO to E2 .
REPAIR circuit 1001 (WH/YE). TEST the system for normal operation.
CHECK THE INSTRUMENT CLUSTER PRINTED CIRCUIT
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
- Are the resistances less than 1 ohm?
GO to E3 .
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
