Thanks I'll try that. I sprayed all the locks with WD40 but just through the door opening may not have gotten it on the right place.

I have a 05 GMC 2500 Sierra that has a drivers door ajar indicator on when the door is closed. The interior lights stay on also, I have to shut off the interior lights manually to keep he battery from going dead. I also have heard the door locks cycling on and off. Looking for answers before I have to take it in to the dealer and spend a bunch.
