So my truck(06 screw) doesn't shut off once my driver door opens. If I open any of the other 4 doors everything works. I really need some help, I've looked into other posts and tore my sill plates back. The purple/violet is in great condition and isn't even spliced from the C pillar to 4" up the rear pillar. I cannot find anything wrong. I've sprayed the door locks with WD-40 and it doesn't work. Any ideas before I take it to the dealership and buy a new door sensor?

Problems:
Radio stays on
Dome lights don't turn on
The gauge cluster doesn't read the door being open.

I'm going to say it's the door switch, in the latch.
