I have found that this is a VERY common fault with the 1998-2003 Buick Century Instrument Cluster. The portion of the Cluster that shows the Gear selection PRD123 and Odometer (miles driven) is a non-serviceable part, requiring repair by shops that specialize in instrument repair, such as SpecMo in Madison Hts, MI, and a few other mail order shops on the West Coast (see EBay Motors). Price for repair and 1 year warranty ranges from $125 to $200. New part can be as much as $400. And that is if you can safely remove the Cluster from the Dash board, and deliver it for repair. And do this without triggering the Airbag (SIR), while you're tooling around in and under the dash. The procedure for getting the Cluster out, is contained in the Haynes Repair Manual, or get a copy at the Library. Pull the SIR fuse (right side, interior fuse box, end of dash panel), disconnect (and as far as I am concerned, pull the main Car Battery), and then disconnect the one or two YELLOW SIR- PAC connectors, under the dash next to steering wheel and above and behind the Glove Box. Even though the Battery is disconnected and/or removed, the SIR (Airbags) have their own on-board power supplies that could trigger the Airbag devices, if badly bumped or ****. To get to these connectors, before you can get to the Speedo/Cluster, will require that you carefully and completely remove each and every panel from the floor, all the way to the plastic dash. You're going to love taking that glove box out, with that retainer strap, wraped around the pinion. This is not for the faint of heart, or the unprepared, under-tooled weekend-warrior. Care must be taken to avoid triggering these SIR's, or serious bodily injury may occur. But if you get the book, read it twice, get a cup of coffee, and proceed carefully, it can be done. Aside from not knowing your speed, engine temperature, or fuel levels, the car can usually be driven short distances without the Instr Cluster. So fill-up first, and top off the coolant, oil, and other stuff. Repair is about 1-3 days. While the parts are off the dash, that will be a good time to wash and Armor-All everything, clean the Duct-work, change the Cabin AirFilter located at the Windshield, under the Hood/wiper arm panel, and use a good ventilation disinfectant system. You will never have a better opportunity solve those pesky odors, and rattles. Cheers!

Where is the reset button to reset the service indicator light after an oil change? I see instructions on how to do it, but I don't know where the reset button is located.

Here's how you get reset the MAINT REQD light:

1) put the key to the ON position
2) press the mileage reset button on your cluster so it shows total mileage (not trip)
3) put the key to the OFF position
4) press and hold down the mileage reset button, leave it pressed
5) put the key to the ON position
6) wait until the mileage shows 000000 and you can stop pressing the ODO button

If that doesn't work, consult this

" Maintenance required"

theres no problem, its set to come on every7500 miles just to remind you to do the service, like oil changes etc, all you do is make sure mileage is showing in display, then turn key off, then push the button that shows the trip mileage hold that button in then turn key on but dont start truck make sure dash lights come on like when starting,okay continue to hold button may take 15 -25 seconds until you see maint light go off, done.hope this helps.

High beams don't work and odometer doesn't show mileage

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

Maintenence light

I get many calls a week for this procedure...
This is really easy! Follow these directions:

Turn the key ON

Look at the odometer, and verify that it displays "ODO" and the total mileage traveled. If it is on "Trip A" or "Trip B", press the black stick next to the odometer to read "ODO", and the total miles traveled.

Turn the key OFF.

Press in, and HOLD the black trip meter reset button, hold it in.
DO not release it.

Turn the key ON; do not start the car.

Observe the Odometer display. The total mileage traveled will disappear, and you will see 5 dashes, then 4, then 3, then 2, then 1 dash, and finally, 5 zeros. Then, the total mileage traveled will redisplay.

Release the black trip meter reset stick.

This completes the reset procedure, and it will be back on in 5,000 miles, to remind you of you next oil change.

Hope this helps!
