Speedo Went Out.

Hey, can anyone tell me where to check to see if maybe i got a loose Wire or something. Because i was driving 1 moment and then the next time i looked at my Speedo i noticed that it wasnt working. Would i have a blown Fuse or maybe Speedo cable went bad on me?

There is nothing electronic about the speedo. It is a cable.

Either the cable popped out of the back of the speedometer housing(unlikely unless you just had it disconnected recently) or the cable broke or the speedometer drive gear in the trans broke.

Best thing to do is check to make sure it is still connected to the speedo.
Then you can remove the cable from the transmisson and attach a drill to it. See if it spins the speedometer. if it does then then the drive gear is bad.
