you most likely don,t want too hear this, but...step one when you buy a corvette, of any year, should always be,
buy a shop manual, or at least down load one, as the paper originals are expensive (BUT WORTH IT)
step two, Id damn sure get out a multi meter and verify all the fuses were good and replace any that were suspect. the service manual will show the part numbers and locations
lights are rather simple to trace and Id start by replacing any light bulbs and verifying current reaches the lights , if not then youll want to trace the wires back to switch contacts
the service manual will show the part numbers and locations
fuses and grounds and electrical connectors on a 15 year old car are suspect, and should be checked and at least assumed to be in need of being inspected tested and cleaned or replaced.
