Our '87's dash lights were doing strange things. The turn signal indicators and the high-beam lights stayed on constantly.
These symptoms drove us to our local Corvette expert, Chris Petris at Corvette Clinic. He diagnosed a dash-light grounding problem, but told us the fix was so simple, anyone could do it. That's good news for anyone who wants to tackle this project at home. Chris says this problem is common, and he gets several questions on how to correct this malady each month. That probably means this quick fix will rid many of you of disobedient dash lights forever. Our replacement bulbs are from Zip Products.
