SOURCE: right door pwr lock pwr
Check the cabling that goes from the firewall to the right door (open the door, and you will see it at the front of the door.)
Look for any damage to the cable its self, then check the connectors.
From tehre I would start checking power to the connectors.

i would say the theft module saw the door trying to be open without the door lock or fob first, once the door lock button was pushed it shut down, it new doors were trying to be unlocked in a theft manner, once shut down it needs time to reset or needs to see ignition cycle with key and read chip in key, smart system isnt it, good luck.

Testimonial: "I thought it was something like that, so I guess using the car door wedge set this into motion and the guy with the keys inside the vehicle is screwed"
Take The Driverside Control panel Off The Door,And Check Conection On The Main Switches,These Vehicles Have Locks On Them, And If They get loose The Stop Working,Also Check The Little Switch Towards The Front of Panel,It Also May Be Loose,Use Caution,The Clips Are Fragile..

this problem i have repaired many times.. it is normally a broken wire in the flexible rubber tube between the door and the doorjamb from years of flexing back and forth when you open and close the door.. i hope that helps

I have the exact problem described. I can't find any brass contacts on the door frame of any door. What door are you referring to? The liftgate is closed and locked, so I can't get to that door frame.
