Can anyone tell me where the sensor is to turn on the coutesy lights when you open the rear hatch? My interior lights don't come on now when the rear hatch is opened; they work fine otherwise. tia

did they work as desired before and not now, or never worked? could be the switch is stuck, or if it is integrated into latch, could be problem in there.

Do you get a "lift gate ajar" message with liftgate open?

If not- the BCM does not know the liftgate is open- and does not turn on the lights- and the problem is in the liftgate switch.....

they work sporadically - sometimes yes, sometimes no. Liftgate ajar light works, just sometimes no interior lights come on when you open the liftgate. Where is the liftgate switch?
