My son was playing ,hes 10,in my disco and somehow he rammed a screwdriver through the speedo and smashed it nicely. I bought a used one from a junkyard and it works great but the odometer blinks all the time . I only had 15 thousand miles on the truck and this one has 35,000, thats not a big deal but the blinking odometer is. Can anyone help please

 

First, I would suggest you go to the dealer and have them set up your used speedo to work in your truck. I would also take in the broken speedo and have the write a work order verifying you have replaced your speedo with a higher mileage speedo so you won't have waranty or sales issues later on.
