I got gas the other day and reset the trip-o-meter to see what my MPG's are. They set to zero but then seemed to stay at zero, further the odo also stopped logging miles. It is a 96 V6. Is there a mini gear that needs to be massaged in the instrument cluster? This is not an electronic odometer. I was wondering if I could mess with it to get it working again, or just get one from a junk yard? Any help you could lend would be appreciated. Everything else on the instrument cluster seems to be functioning properly.
