I just got a 2002 z28 convertible and my ip dimmer switch keeps blowing. It's annoying not having the gauges illuminated at light. I've looked through other posts and others seem to have the same problem but no common solution. I was wondering what manual has good electrical schematics so I can start troubleshooting the problem. Does alldatadiy.com contain electrical schematics or would it be better to get a printed manual?
