The trip computer on my 99 LT failed a while back. Since then I have tried to track down a possible cause but can't find anything obvious. The thing just quit one day on a rainy ride. Does anybody out there have an idea what a cause could be and are they fixable? I currently have the plastic off and have made sure the connector plug is clean but other than that there doesn't look like there is much that can be done to the actual unit. Anybody got a used one that works they would like to part with?
