Any idea why the dash lights would stay on for 20+ min. after all doors have been closed? I got home tonight and left the doors open for a while (30 min?) but after unloading everything and shutting all the doors, I could see that the gauge lights were still on, including the illuminated LCD display between the speedo and tach. I finally gave up waiting and hit "lock" on the remote to shut them off, but I'm curious why this would happen. Anyone else noticed problems with this?
