Hi! my interior, footwell, and mirror lights have stopped working when opening the door or unlocking the car. I thought maybe a fuse, but when I switch the light on manually it works fine. Just no response when I open any door, or unlock the car, or turn the ignition off. I have checked all of my ground (what i found) in the interior, all looks good, all of my relays have tested, it works too. All of my lamp wires had 12v on, but no ground on any time. Any ideas? Thanks!

The gem module provides the ground when the doors open. So either wiring broken between lamps and gem or gem module internal failure. 

You can check the door switches but unlikely they all failed at the same time.
