Have you checked the Bulbs are OK and the socket contacts are good and clean?
You sure you identified the Low Beam relay correctly...on the rear of the Junction Block.....small relay by itself on the lower rear of the block?
If you remove the Low Beam Relay and briefly jumper pins 30 and 87 together inside the relay socket then the this will test the wiring run from the Low Beam Relay all the way to the lamps....the low beam lamps should light unless the bulbs are blown or there is a bad contact somewhere.
If this does work only with this jumper in place then the BCM may have a problem as it controls the grounding of the Low Beam Relay coil.
