The odometer on my 87 SDL had stopped working so I removed the instrument cluster, fixed the odometer and installed the cluster. After installing it, the radio won't come on unless the door is open. I double checked all the connections for the cluster and it seems to be working fine except the clock stopped working. Also with the door closed I can't turn on the overhead/reading light but it works fine when the door is opened.

Any ideas or suggestions?

Thanks,
Brian
