My odometer doesn't work but the speedometer does... I've tried thumping the reset button but it's still stuck... I mean it's great my truck isnt getting any older BUT.. I'd really like to be able to tell how far I'm getting on a tank of gas.. any thoughts?

 

found the problem... a small rubber worm gear inside the odometer assembly had broken into small pieces.. a 1/2" long gear.. costs $28.00 YIKES!
