Q: Is the speedometer integrated into the instrument cluster panel and what should be done in case of a failure on Nissan 300ZX?A: The speedometer is one of the instruments incorporated in the instrument cluster panel, and, therefore, can't be replaced selectively. Should there be a failure in these items, then the whole of the instrument cluster panel has to be pulled out and replaced. The user should contact his local Nissan dealer to set the new mile age on the new speedometer to match the reading of the previous speedometer to be replaced.
