DRL not working / All fuses, relays and bulbs good

[Inspignant]

Just noticed that I had no DRL's when I went to do the mod for the Headlight and DRL both on mod. I have checked both bulbs, good. DRL fuse, good. Relay, good. Light sensor in dash, good. I understand that for the DRL's to work you need to have the engine on and in Drive. What else could I be missing? Last year I installed Xenon HID headlilghts but my DRL's were functioning.

double check your mod connections between each relay. You also may have the wire in the wrong direction as the mod requires the use of a diode.

the final issue could be the HID's may not allow this type of mod.

I will check the HID relays that come with the kit. I need to mention that the DRL's used to work when I first installed the HID's. I also have not done the mod yet for the DRL and Headlights on at the same time yet since I noticed the problem with the DRL's not working anymore.

New DRL bulbs
New DRL relay installed correctly
New Fuse
Working Light sensor (checked with flashlight at night) Headlights go off but DRL's dont come on.

The HID's should be wired completely separate from the DRL's and should have nothing to do with them not working.

As FYR said double check your wire and diode that it's in the right direction for the DRL mod. That honestly is the only thing that has changed and they no longer work.

Thanks guys, I will be digging into this, this weekend. Seems I am having more issues now. The Cruise control is not working now, and it worked last week. Will update with findings. Thanks again.

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.
