2001 Grand Am GT with 52,000 miles. The security light came on while driving. I stopped, turned it off, and it started right back up with no security light. However, the interior lights stay on until i start moving, and the doors won't lock with the door button, only the remote. The parking lights won't flash when you lock/unlock, and there's no horn. When you turn the car off, the interior lights stay on indefinitely, so we had to unplug them. Any ideas?
