I have a dome light and a reading light that are not working on my new (to me) H30. Bulb replacement didn't help, so I assume the fixture itself needs fixing or replacing.Any suggestions for troubleshooting? Should I just put new fixtures in? The former owner said the dome lights go bad sometimes; he replace a few of them already. If I am to replace, is this just a matter of replacing the fixture itself - reconnecting the old wires to the new fixture at the fixture, or do I have to run new wires all the way to the panel?Any suggestions for how to do this are greatly appreciated. I am no electrician.Thanks!
