The odometer in my 2000 Buick Century is not lighting up. What can be done? The Buick dealer says I have to have the entire cluster replaced. Only the odometer/shift cluster is not lighted. The rest of the clusters are ok.

There is a bulb that you can replace and to get at it there are two screws if i remember right that you need to take out for the actual cluster unit and the rest you can pop off with a screw driver.

Have a good one!

The instrument cluster in the 2000 Buick Century features an analog odometer that is back-lit, making it possible to see during night driving. Over time this light has a tendency to burn out, which can make for unsafe night driving as the driver will not be able to see all of the information usually at his disposal while driving. Replacing this light takes some time and requires you to be careful when disconnecting the wiring harnesses.

1. Pry off the fuse box over on the passenger side and then remove the screw inside with a screwdriver.
   
2. 2 Unscrew the screw on the far right side of the dash panel and then remove the panel.
   
3. 3 Remove the two screws underneath the temperature controls and then pry off the plastic trimming.
   
4. 4 Unscrew the one screw on the dash panel underneath the steering wheel.
   
5. 5 Disconnect the wiring harness from behind the interior panel and then pry off this entire panel.
   
6. 6 Unscrew the four screws around the instrument panel.
   
7. 7 Pull out the instrument panel and disconnect the wiring harness on the back of it.
   
8. 8 Twist the back of the bulb counterclockwise and then pull it out.
   
9. 9 Unscrew the old lightbulb and then screw in the new one.
   
10. 10 Reverse the steps to reassemble your dashboard.
    

You have to replace the cluster or have it rebuilt. The odometer and trans indicator is lit by led's

Wrong! Non of the above. I just fixed that problem. The problem is loose resistors on the instrument cluster's printed circuit board. It is four bigger resistors parallel to each other. Re solder them and your odometer cluster is back to perfect.

you will need to remove the cluster and have it repaired call your dealer they will know were to send it to repaired

The cluster will have to be sent out for repairs or exchange by a dealer or see Model Electronics.

Sadly no, there is no fuse or bulb to replace. You either have to send the instrument cluster out for repair or replace it with a new unit from the dealer. You could also obtain a serviceable one from a salvage yard. Most shops should be able to replace the instrument cluster or advise who can repair it.

This is a common problem.
After many hours of internet research, I stumbled upon the only repair suggestion that sounded reasonable to me.
I performed the repair and it was successful.
I now have odometer and prnd321 lights.
There are four small resistors on the upper right section of the instrument cluster circuit board (just to the left of the tripmeter reset).
The solder connections of these resistors become corroded over time. Three fell to floor when I ran my finger over them.
I replaced the four resistors with 1/2 Watt 150 ohm resistors (soldering skills are required).

it will register the car it came out of and you can not change the milage you would nrrd to send it out
