    Yesterday, the Gauge/idle, 20 amp fuse blew on my 1990 Blazer. After I replaced the fuse, I noticed that the electronic speedometer was pointing at 85 MPH and was now not working. I pulled out the speedometer and I can’t find anything wrong with it or the flex connectors . Does anyone have any ideas as to what I can do ? If the speedo is shot what would be a good replacement ?
