This solution will be of great help to you,even in the case of future or other dashboard problems; Instrument cluster consists of electronic analog gauges, various warning lights, and optional tachometer. Vehicles equipped with tachometer have an electronic vacuum fluorescent transmission range indicator (PRND3L),odometer and trip odometer display. Vehicles without tachometer are equipped with a cable-operated transmission range indicator. Instrument cluster is equipped with the following warning lights: Battery voltage. Cruise (speed control). Door ajar. Fasten seat belt. Lift gate ajar. Low fuel level. Low windshield and washer level. Traction Control. The Body Control Module (BCM), which receives input from various sensors, sends display information to instrument cluster and operates gauges. Instrument cluster incorporates a self-test diagnostic feature to identify electronic problems. BCM, Powertrain Control Module (PCM), and Transmission Control Module (TCM) are continuously monitored by the diagnostic system.
SELF-DIAGNOSTICS With ignition off, press and hold TRIP and RESET buttons while turning ignition switch to ON position. Continue to hold TRIP and RESET buttons until odometer window displays CODE (approximately 5 seconds). If problem exists, system will display diagnostic trouble codes. See DIAGNOSTIC CODE CHART table. If no problem exists, Code 999 (end test) will be displayed. DIAGNOSTIC CODE CHART CodeDescription 110.......Cluster Memory Fault 111.......Cluster Calibration Fault 905.......No CCD Bus Message From TCM 921.......Odometer Fault From BCM 940.......No CCD Bus Message From PCM
After diagnostic code display ends, instrument cluster will go into each of the following tests in order: Dim test. Calibration test. Odometer segment test. Electronic Transmission Range indicator segment test. Dim Test CHEC-0 will be displayed in odometer window. Instrument cluster will dim Vacuum Florescent (VF) display. If VF displays do not dim, a problem in instrument cluster exists. See BODY CONTROL COMPUTER TESTS in BODY CONTROL COMPUTER article. Calibration Test CHEC-1 will be displayed in odometer window. Each of instrument cluster gauges will move sequentially through each calibration point. See GAUGE CALIBRATIONS table. If gauge needle is not calibrated properly, a problem in instrument cluster exists. Odometer Segment Test CHEC-2 will be displayed in odometer window. Each segment of odometer will light sequentially. If any segment does not light, replace instrument cluster. Electronic Transmission Range Indicator Segment Test CHEC-3 will be displayed in odometer window. Each segment of electronic transmission range indicator will light sequentially. If any segment does not light, replace instrument cluster.
It could be a fuse, which may be located in a panel under or either side of the dash. Possible other location in a panel/box in engine bay.
If this is out of your experience, an auto electrician may fix it quite cheaply.

on many buicks and impalas there is a problem with the wire resistors falling off the circuit board! You will see four resistors upper right if any of these has fallen off they need to be replaced, Good news is you can replace them yourself ! go to your electronic supply store and buy 151 surface resistors and replace them ! These are 50 ohm and don't get hot and fall off. use a 15 watt soldering iorn. Don't want it to hot! Repace all 4 and wala it should lifgt back up! Douglas Noack texasinstrumentcluster.com
there are 2 large terminal plugs with the wiring for all the instruments that are plugged into the back of that panel. make sure they are snug and in place. You reach in and under but it may easier to "simply" remove the cluster. 4 screws hold it in place accessible form underneath and with a long phillips screwdriver and lighting.
