Hello my name is***** can help.

The DRL are controlled by the body control module.

If you can post your VIN#.

I will see if there is a program to enable the DRL.

I looked at the BCM programming There is no choice for turning on the DRL.
Have the dealership technician call Techline at 1-***-***-**** and request a new calibration for the truck body control module (tbcm) that will disable the DRL's. Recalibrate the TBCM with the new calibration.
I believe they can enable them also through programming.

Dealer will charge me a lot for this. I was looking for easy, fast and cheap method.This isn't worth it.
Expert:  GM Bob replied 1 year ago.
you want to try to wire around it and not have the BCM turn them on?
If you wire around it you will have to put a switch some where to turn them on.
If you want to do this I will have to post a schematic. We will need to know if there is a wire at the BCM to turn them on.
Let me know if want to do this.
I could put in for a refund.
Thank you
