The radio/electrical on my 09 JKU Rubicon used to always stay on for a bit when I removed the key when the doors were off or until I opened a door if they were on. Now it all shuts off immediately when I turn the ignition to off. I can't roll up the windows or listen to the radio until I turn the key at least one position. Any ideas as to why this would have changed? Is there a way to get that feature back? Thanks!
