Do the loading lights come on the tailgate ?
Do the cabin lights come on normally when tailgate is open?
Any indicators of door ajar on dash?

You can save battery by putting dome lights on mechanic mode by holding de light for 3 seconds.

Oh also: try this: lock the doors twice (clown nose will blink fast for a few seconds): that disables the motion sensor. If the alarm doesn't sound and lights stay off that means something wrong with motion sensor circuit.
