No headlights

I have a 00 grand caravan and my lowbeams stopped working. I have parking lamp function and brights. I replace the headlight switch and that did nothing to help. I notice that when I turn the park lamps on, I hear the relay clicking and they light up along with brights when activated. When I put it to the low beam position(headlights on position), I do not hear the relay clicking from the relay and fuse center under the hood like the other lights. I tested the bulbs against the battery and the low beams are good on the bulbs them self. Any help would be great. Could this be a problem in the relay box or the BCM?

Have you tryed a different relay. Has the multifunctional switch been tested??? Does it have DRL's?

No daytime running lights and yes I've tryed different relays. Can it be something inside of the relay center that can be corroded?

I also replaced the headlight switch.

Turned out to be the BCM
