Thanks for taking the time to reply to my post I'll give that a try and let you know how I get onAre you still able to turn on other 'ignition on' only circuits such as headlamps? If so I would suspect a faulty ignition switch. Another distinct possibility is the body control module below the RH a pillar.
I would try disconnecting the ignition switch connector first and seeing if the dash lights go out. If they do the ignition switch is most likely to blame.
