Instrument cluster 2001 buick century

There is no fuse...i had the same problem on my buick regal (2003). You need to take dash apart and take the instrument cluster out and have it repaired. If you look on ebay under " instrument cluster repair" you will find people / companies that do tjis and you will see that it fixes the symptoms you are describing..btw...it is unfortunatley a common issue

is it on the dash?...digital?..near the odometer?

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.
    

the trim around the cluster has another peice of trim below it on both sides of the steering collum. at the bottom edge of this trim are phillis screws. remove this trim and that will exposethe screws that hold the cluster trim, above the cluster in the same trim is a few more screws that hold the trim on then theirs also snap in clips that you just pull the trim straight out. once removed theirs screws holding the cluster ito the dash (4) once these are outand the steering collum tilted down as far as it will go you can pull the cluster out and tilting it towards you you can reach behind it and disconnect the electrical connectors, then you can work it towards the center of the car and out.

Remove the 5 mounting screws from the instrument cluster trim plate and remove the trim plate. Remove the 4 mounting screws from the instrument panel face plate and remove the face plate.Remove the instrument light grid from the center of the cluster. From behind the instrument cluster reach behind the speedometer and disconnect the speedometer cable by releasing the tab. Pull the cluster forward just enough to detach the "check engine" light bulb from the center of the cluster. Remove the instrument cluster from the dashboard.

Left hand side of dash behind instrument cluster with your speedo, instrument cluster needs to come out to replace it.

I had this same problem and I removed the long plastic dash piece that goes from door to door (after removing other pieces which hold that one in place) and then tilt the steering wheel to the lowest position. turn the key and put the car in gear 1 then shut the car off -this enables you to remove the instrument cluster, which is held in by 4 screws. Unclip the back of the instrument cluster and remove the circuit board. On the board to the right of the speedometer are 4 resistors which look like tiny black cylinders -these need to be replaced (if they haven't already fallen off the circuit board). I was missing two and I just touched the other two with my finger and they fell off. I soldered onto the board 150 ohm, 1/8 watt resistors ($1.99 for a packof 5 at Radio Shack). This entire process took me about 30 minutes. I put everything back together in the reverse order I took it apart and my instrument cluster, odometer and gear-shift indicator works fine.

You have to remove the dash but it is VERY simple to do.

Remove the fuseblock cover on the end of the dash on the passenger's side.
Once removed, remove the screw holding on the end of the dash.
Now, next to the glove box, to the right, remove the one screw on the bottom. Then remove this panel by pulling it out (it will now be held on by two clips at the top.)
Now, looking at the temperature control cover, remove the two screws from the bottom of this. Pull it off. It also is held on by two clips.
Now, below the steering wheel, remove the one screw from this panel (on the right). On the left there is a "plug" holding it in place, Pop out this plug. I think there are a couple of clips now holding this on at the top.
Now that you have all of that pulled out, pop the dash out. At worse, it is held in with clips.
Now that you have this out, there are four screws holding in the instrument panel. Take out these four screws. You will find one electrical cable connected to the cluster. Pop that off of the cluster and you now have the entire instrument cluster in your hands.

I've had to take mine out to figure out why my gear indicator/odomiter would not illuminate (Buick told me it was a light). I can see where this encased LED has a short (black mark). It is soldered onto the board. Looks like I have to purchase a repaired board.

I hope this helps.

Are all the lights in the dash out? if not, it is the bulb, the bad news is you have to remove the instrument cluster to replace the bulbs, there is no access from the rear that allows you to get your hand in there.

No. 2001 to 2003 are interchangeable. I am currently looking to replace mine on a 2002 and have consistently been told those years are the same. These babys are pricey, perhaps you can trade your 2004 for one that will work.
