u can take apart the gauge cluster and take like a small sewing needle and give the odometer a little help. then try driving around it should work fine. sometimes they get jammed or stuck and cant roll over. keep in mind this is one thing in ur car thats working all the time u drive. so they're bound to get jammed once in a while. happened to me many times before i bought my jdm gauge cluster. if ur speedometer isnt working at all either then you need to change the whole speedometer. as far as the tach its kinda wierd but i have extra rpm gauge tachs around. let me know if u want it. they all work. only thing i dont have is the speedometer odometer part. used em all trying to get my jdm assembly to work. let me know.
