odomter ligth

my roommate is buying a 99 sunfire 4 door 2.2 is thus a good car and also the odometer does not ligth up so it does not show mileage it is the LED type so how do i repair that he has has asked me to repair it any tips and how tos?

My 2000 sunfire did the same thing, i went to the junk yard and got a used cluster for $60.00, the dash is real easy to take off. it's a litle light bulb that burns out it was known to do that in the 99 and 00 sunfire's the guy at the junk yard told me.
