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.
