The odometer is not working the are six small straight lines that blink off and on displayed where the milelage should displayed

Odometer
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.

Did you try to reset it.

Turn car off, hold in odometer reset button, turn key on (don't start) and wait for it to reset. Normally you will see small lines counting down on the odometer display.

When if you exceed the limits of the odometer, in this case by driving one million miles, the odometer will start again at zero. Before the 6 digit odometers became common, you would see many cars that were over 100,000 miles and the odometer had "turned over". Million mile odometers were not common until the early 90's, so you will still see cars with the 5 digit odometer!

If there are any problem in your odometer, you can fix it by the a Odometer Correction Tool

I have the same problem as bestdad2000.
on my 2001 Buick Century the odometer and trip meter do not light up, but the rest of the instument panel does?? I have been using the trip meter for trip milelage as my gas gage has stop working properly. Help!! [email protected]

Make sure the car is in "off" position.
Press and hold the odometer button.
While pressing the button switch the starter to 'on' position.
You will see 5 lines appearing on the odometer display. The lines will vanish one by one.
Release the odometer button.
Light will be off!!!!!

(Note: each line on the odometer display represents1000 miles. I5 lines mean 5000 miles, meaning that the light will be turning on after 5000 miles. To reduce the mileage to, lets say 3000 miles, realease the odometer button if 2 lines are vanisahed)

With key off hold down the trip reset button and turn key on while holding it. You will see 5 small lines counting down to 0 on the odometer display. When it gets to 0 it is reset.

defective electronic speedometer, and that is the straight answer from a Ford dealer technicain

the B is for your trip meter not your odometer. the sx4 has 2 trip meters a and b that share the display with the odometer., yours is on trop meter b. press in the little black button next to the display to cycle through odometer, trip a, or trip b.

I don't know if it's the same as my D150. But it's pretty simple:
1) remove about six screws from under the upper lip of the dash face bessal and one under the overhand above the radio.
2) carefully jimmy the bessal straight out. It has about four spring trim-clips that will release under pressure.
3) this exposes the speedometer instrument cluster. It is one big assembly (speedometer, fuel, temp and elctrical guages, etc) attahed with about six #2 phillips face screws. Remove these.
4) There are three back contections on the cluster: two electronic and one mechanical. Carefully start to pull the cluster out along the steering column until you see the shift indicator control line ( a small fishing-line with a hook on the end) attached to a small steel flang on the base of the steering column. This can be unhooked with your fingers or needle-nose pliers.
5) as you pull the cluster further out you can reach behind and unplug the two electronic connections. The round one simply pulls straight out. The last (rectangular) one has a pinch latch you need to compress to allow the plug to come out.
your finished!
