What is the power sourcefuse that links the 2002 b3000 wipers and speedometer together?

The power source that links the wipers and speedometer in a 2002 Mazda B3000 is typically the same fuse in the fuse box that controls the instrument cluster and wiper motor. This is often referred to as the "Wiper" or "Instrument Cluster" fuse. If either system is malfunctioning, checking this fuse for continuity is a good first step in troubleshooting. Always refer to the vehicle's manual for specific fuse locations and ratings.
