Hello,

It sounds like the BCM is going out, but to be sure we must scan the CAN. Here is a video that shows how and the headlight wiring diagrams so you can see how the system works with the BCM location so you can replace it. It must be programmed to the car which will run about $130.00.

I would try removing the electrical connector from the BCM and then plug them back in again this can sometimes fix a bad connection. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
