Yesterday I noticed my driver side sidelight was out with no messages in the cluster about it.

I swapped in a known good bulb that also won't work. When I turn the headlights on, and hit the plug with my multimeter, I see 12v. If I turn the hazards on, I can see the voltage and continuity flashing on the multimeter along with the other lights so I know the circuit is getting 12v power and being controlled by the LCM.

Once I add any type of bulb to the socket, all power gets cut (verified by back probing on the connector). As soon as a bulb/load is removed from the circuit, power is restored. Does this sound like an LCM issue where it's cutting power? Any thoughts on where to start troubleshooting? I plan to hook up INPA tonight to see if there are any codes.
