    Looked around internet for others with same problem. Others had replaced headlight switch. But I noticed one said replacing rear defroster relay fixed his. They're different circuits he thinks but he had noticed the rear defroster quit working; he may have meant it quit when the fuse blew that caused the dash/taillights to quit.

    Anyhow, before looking at the circuit diagrams, I'd suggest pulling the relay for the rear defroster. See if the problem goes away. No charge to just pull it--don't replace unless it fixes problem.

    I don't understand why the ignition switch might cause the problem to show up.

    Good luck and hope that works for you.
