told speedometer problem caused by blown fuse

Hello, do you have a conventional speedometer, or a digital one? This makes a difference. The conventional speedometer is driven by a cable. The electronic digital one is fed information via a vehicle speed sensor. If you have digital, and it's reading "0", you would test the vehicle speed sensor circuit first. If it is digital and does not illuminate at all, it can be the cluster itself. Check circuit protection (fuses / etc) first before replacing parts.
