ok i just got my car used and the mileage is blank and some1 told me that i have to replace a bulb in it does anyone no how.
 
either 1) smack the dash to see if it comes back and if not 2) you need to buy a whole new cluster
 
 
You bought a used car with unknown milage?  I hope you didn't pay much.

Sold 6/30/06.
