Hi Guys,

I now know more about my '87 300D instrument cluster than I thought I ever would. However, when I disassembled the odometer module from the cluster, I couldn't figure out what was wrong with it. It seemed to operate OK. But after I re-installed it, the trip odometer worked for only about a mile, then quit again. The main odometer works fine. Any ideas why the trip odo doesn't work?

Thanks!
