DRL not working / All fuses, relays and bulbs good

[glennf1]

I just did this mod too and the same thing happened. I metered it and there is no longer voltage coming from the BCM. Apparantly, the voltage going backwards to the BCM from doing the mod fries the transistor that switches it. Now I just have the DRL on with the headlights. I'll just live with it instead of buying another BCM module. Others have gone years with no problems.
