I have a 91' fullsize blazer the other day the speedo wouldn't work and then the brake light came on in the dash at highway speeds the brakes would start pulsing when pressed and the speedo will just bounce every now and then if I shut the truck off and restart it brakes work fine until about 35 mph I pulled the speed sensor and it looked okay I changed it out for another sensor I had and now the speedo works but at about 15 mph if you gradually get on the brakes speedo drops to zero but the brakes work fine has anybody every had this happen
