Don't know what problem you are having , could help you out if you listed problem . The instrument cluster is a electronic module ,has a microprocessor inside . The gauges display info. come's to the instrument cluster via class 2 serial data network from the PCM/ECM - engine computer . Factory or professional scan tool can communicate with the instrument cluster , view data , read DTC'S - diagnostic trouble code's . If you don't know this , your best bet , take it to a qualified repair shop.
You won't find wires for fuel sending unit , this info. is sent to the PCM/ECM an sent over single wire class 2 data bus.

Engine Coolant Temperature Gauge
The Power Control Module (PCM) broadcasts the coolant temperature value via the class 2 serial data line. The instrument cluster compares the temperature data using a 16 point look-up table in order to determine the needle deflection. A smooth filter is used in order to secure a continuous response. The instrument cluster drives the temperature gauge to C (cold) under the following conditions:
• The temperature data is lost.
• The PCM is in a state of health fault.

Fuel Gauge
The Powertrain Control Module (PCM) broadcasts the fuel level data via the class 2 serial data line. The instrument cluster compares the fuel data using a 16 point look-up table in order to determine the needle deflection. A smooth filter is used in order to secure a continuous response. The instrument cluster may determine if a low fuel condition is present. In the event of a low fuel condition, the following conditions may occur:
• The instrument cluster shall activate the LOW FUEL indicator.
• Send a chime message to the Body Control Module (BCM).
The instrument cluster may drive the fuel gauge to E (empty) under the following conditions:
• The fuel level data is lost.
• The PCM is in a state of health fault.

Speedometer and Odometer
The Vehicle Speed Sensor (VSS) is a gear-driven permanent magnet generator housed in the transaxle. The sensor generates a sine wave output with a frequency proportional to the vehicle speed. The Powertrain Control Module (PCM) uses this information to generate a vehicle speed signal that is sent through the class 2 serial data link; the instrument cluster then is able to utilize this data for the operation of:
• The speedometer
• The odometer


Data Link Communications Operation
Class 2 Serial Data Link
The Class 2 serial data link is used so the following modules can communicate data with each other:
• The Body Control Module (BCM)
• The Electronic Brake Control Module (EBCM)
• The Inflatable Restraint Sensing and Diagnostic Module (SDM)
• The Instrument Panel Cluster
• The Powertrain Control Module (PCM)
• The Heater-A/C Control

SOURCE: instrument cluster removal 2001 buick century

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.

If your car runs bad with an EGR code then I would suggest that the EGR valve be replaced. I would like to know what code was set on your computer. It would help greatly. When the EGR malfunctions, you will have rough idle and possible stalling. If you have a code indicating EGR it may also condem the cat converter.Please show any codes that are set. Thanks Moe

SOURCE: The odometer in my 2000 Buick Century is not

Yes the dealer is right. there are several places that rebuild these for less than a new one. The dealer should be able to send it out or get a rebuilt cluster. If the dealer doenst want to help you, find a good repair shop, they usually have a place they get clusters from.

Heat is stuck on on driver's side/dual control/2003 Buick Century


You will need to replace the control cluster. It's pretty simple, two screws down behind ashtray and pull the plastic cover off. Two more screws and the cluster comes off. Undo the wire harness and the cluster is out. You can get a different cluster at a salvage yard got about 15 bucks.

How to take out instrument cluster in 2000 buick century odometer lights out


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.

How to chnge dash board light


If it's in the cluster, see procedure below for removing cluster. If this isn't what you needed, please get back to me.

1997-00 Buick

CAUTION All models covered by this guide are be equipped with a Supplemental Inflatable Restraint (SIR) system, which uses an air bag. Whenever working near any of the SIR components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SIR, as described in this section.
  1. Disconnect the negative battery cable. Disarm the SIR system, as outlined in this section.
  2. Remove the instrument panel cluster trim plate using the following procedure:
    1. Remove the instrument panel access hole covers from the instrument panel using a small flat-bladed tool.
    2. Remove the screws from each end of the instrument panel cluster trim plate.
    3. Remove the screw(s) from the lower edge of the right side of the trim plate.
    4. Open the instrument panel compartment (glove box) door.
    5. Pull the right lower trim panel plate from the instrument panel.
    6. Pull the steering column tilt lever and tilt the steering column to its lowest position.
    7. Grasp the instrument panel cluster trim plate at the right edge and slowly pull, working to the left to release the retainer clips. Remove the instrument panel cluster trim plate from the vehicle.

      1. Remove the push-pin retainers from the top of the cluster.
      2. Rotate the instrument cluster rearward and disengage the locating pins on the bottom of the cluster from the instrument panel. Detach the electrical connectors and remove the instrument cluster from the vehicle.
      3. Installation is the reverse of the removal process. Use care to make sure all installation clips are properly located. Do not over-tighten any screws or they could force their way through their holes and the panel will not be held properly. Squeaks and rattles may develop later.

      WHAT DOES THE INSTRUMENT CLUSTER ON A 2000 BUICK CENTURY CONTROL? WHAT CAN GO WRONG WITH A BAD CLUSTER?


      Instrument cluster "controls" nothing. It gives you information from items that are being controlled and it gives you the results of what is going on...speedometer informs you of your speed...flashing light on the left informs you you have selected the turn signal arm to turn left.

      What is the problem you are having?

      Odometer light out on buick century not working


      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.

      None of the instruments in the cluster work (Gas gauge, speedomot


      It is possible that the connector came off the back of the circuit board behind the speedometer. Do the lights work IN the speedometer and gauges? Could also be that the ground wire loosened up under the dash, usually on the drivers side. Just some suggestions that I thought might help. Best wishes to you.
