A little research about your odometer turned this up.
"A little red gear operates both the odometer and trip odometer. This gear is apparently vulnerable to interior heat in warmer climes, and the teeth break off with depressing regularity, rendering both odometers inop. This is a well-known vulnerability in our Saturns. Its about 1/4 inch in diameter, and fairly expensive (around $29.00, depending on where you order it).
Replacing this gear is not "simple" by any means. But it can be done by somebody fairly adept with hand tools, and should fix the problem permanently."
Good luck. : )
