Hey guys/gals, got a unique problem with my overhead light cluster on my '95 GL. A couple of months ago the lights ceased to function...properly. They only work when either of the two courtesy mirrors are opened and even then they don't work according to their respective switches. If they were capable I'd say they're on drugs

. Anyone ever experience this before? I thought it might indicate a blown bulb, similar to a signal light going, but all the bulbs function at a fraction of their normal brightness. Thanks.
