I have a 1999 Mazda b-3000 4x4 truck and the speedometer stop working. Are there fuses related to the speedometer that I can replace. If so where are the fuses located in the vehicle.
To replace dash lights on a Mazda B 3000 first disconnect the battery and remove the dashboard. Unplug the cluster wiring and carefully remove the display. Replace the lights.
I was told the computer was bad. I would test the computer first. It may also be the ignition module. I had the same problem with my '94 Mazda truck. It would be running fine and then just shut off. Also had trouble starting up every now and again. Usually i could just tap on the ignition module several times and it would start right up.
