Odometer issue and not turning over

Not the Key but the ignition itself. Replace teh ignition module where the key is inserted to start the vehicle and that should resolve the issue.

turn the key on. press the odometer/trip button until the odometer is displayed. turn the key off. press and hold the odometer button and turn the key to the run position (do not start). The odometer should change from a number to all dashes ( - - - - - - ). One by one the dashes will disappear then the display will change to all zeros and then will change to the regular odometer reading. Once the regular odometer is displayed let go of the button and turn the key off. The maintenance light will now be reset.

Make sure the odometer is set to odometer and not tripmeter.

Stick the key in the ignition. Hold down the odometer reset button, turn the key to the on position(don't start the truck) and hold it until the lines are gone..

You will automatically see a few lines in the odometer that will start to go away. Once all the lines are gone, the counter has been reset.

If you are talking about the odometer display does not show numbers, here is a detailed instructions on where to find the cold solder joints at :

This is if the cluster lighting still works, but the display is blank. Don't know if you mean the gauges in the cluster do not work.

I had the same problem with my Odometer in my 01' Regal. The dealer will quote you some outrageous price for a new instrument cluster. There are a bunch of people on Ebay that you can pay around $100 and they will repair it for you. Or, if your husband is pretty handy you can fix it yourself for about $2.00. All you need is a pack of resistors from RadioShack and soldering gun. I did it myself and with this videos instruction it only took me a little under an hour and $12.00.

As for the service light, I don't know what you had repaired, but to get mine off I had to get a dealer to reset the computer (about $100 or so).

With the battery connected?
With a Digital Odometer: Turn the Key from Off to On (not start) three (3) times, On the third (3rd) time leave it in the On (not start) position. The Codes will appear in the Digital Odometer Screen. When it is finished it will show "PdonE".
It is on the 2001 Dodge Caravan.
Without a Digital Odometer?
Turn Key the same way and leave the same way.
Watch the Engine Light (yellow) and count and record the blinks. Do it a few times to get the count correct.
These are 2-digit numbers. The last set is 5-blinks and 5-blinks indicating that it is complete.

would change the ECU with the chip from the key from a car in scrapyard ,but before you get carried away try another seperate earth on the back of the speedo printed circuit board ,i wouldnt mind betting this is your problem

Replace battery for sure then check the odometer connections at both ends, panel side and tranny side for loose connections, usually a theaded screw in type.

sounds like a instrument cluster fault
