Re: Odometer does'nt light up
The bulb is most likely burnt out if it is the style that has black letters with white background that goes around in a circle. if it is digital then there could be something wrong with the dash cluster it all depends on how old the vehicle is.

The odometer is an electronic digital display. Digits displayed are illuminated by the odometer backlight bulb. The odometer backlight bulb brightness is controlled by class 2 messages from the BCM to adjust the display for daylight and instrument panel dimming operation. The trip odometer and total odometer will show in this display area. The push button in the lower right side of the speedometer is used to toggle between the trip and total odometer readings. To reset the trip odometer, push and hold the button down for at least two seconds. The total odometer display has six digits with no decimal display. The trip odometer has four digits including a decimal point and indicates tenths of a mile or kilometer.
The body control module (BCM) stores the vehicle mileage. If the BCM fails, the cluster will display the last valid mileage that was sent before the BCM failed. For replacement of the BCM refer to the BCM section of this service manual. Replacement instrument clusters do not require odometer pre-setting before installation. If the instrument cluster is replaced, the mileage stored in the BCM will be sent to the new cluster via serial data, and shown in the odometer display.
Your best bet , take it to a qualified repair shop.
set the mileage when the odometer is showing. put the key to off position. press and hold the reset button then turn the key to on position, do not start. then continue holding the reset button until the reading stops to zero or blank. turn it off, that should reset the light indicator
First check the bulb, alot of the time if a bulb is burnt out it will show something on the dash, example if a directional bulb is burnt out the dash will show a solid lit directional on the dash. Next check the bulb socket for corrosion, some times you will need to either grease it, bend the tongs up or just replace it. I hope this helps don't be afraid to ask if you need more help!
well if you hold the multiswitch back do they come on if so the multiswitch is bad and the odometer is it only mileage or is it everything ex.P R N D 2 1 well if those dont show either and its just a blank spot then does the dimmer switch work for everything else if not well dimmer switch may be bad does the rest of the instrament panel light up? if not theres a 20 amp fuse to replace because ur tail-lamps wont work either and it that is not it you probably either have to have the instrument cluster repaired or go to the scrap yard and get one of which is common for buicks of this year
reset: turn ignition on...push odometer button till it displays mileage on car...not trip milage but actual mileage. Turn car off. Open driver's door, press and hold odometer button....turn ignition to on....hold odometer button for 10 seconds....odometer display will show -----,----,---,--,-,0000000....maintenance lights are reset...lights will come on every 7500 miles to remind you to change oil and check fluids etec....
