Default Need help to reconfigure/disable Daytime Running Lights on a 98 GMC Suburban

I have a 1998 GMC Suburban where the Daytime Running Lights are the low beam headlamps. The problem is that I live in Florida and the constant heat of the headlights being on during the day is causing my headlight lenses to get a white haze that I can not remove. This haze blocks the light output at night causing visibility issues. I just bought my second set of replacement headlights in 4 years and I want to keep this from happening again.

1. Can I reconfigure the DRLs to activate an aftermarket set of lights and keep the headlight functionality the same is it is currently? In other words, is there a control module that I can disconnect from the low beam headlamp system and redirect to another set of lights?

2. If #1 is not possible, how do I deactivate the DRLs without affecting any other systems. There is a fuse for the DRLs, but I don't know if there is anything else on the circuit. I can deactivate by setting the park brake, but this activates the brake light so jumping that switch is not an option.

My preference is to keep the DRLs on an alternate set of lights, but my night time visibility is more important as I live in the country where there are very few street lights.


Thanks

Rick

There is a relay in the underhood fuse block that you pull out. I am not sure of the location but if you look at the label on the lid of fuse block there is a listing 'DRL'. Simply pull out that relay and they are now inoperable. Headlights (high and low) still work as normal with the switch. The relay you want to pull has a solid white triangle with a line through it, it looks more like a fuse. Hope that helps you out.

I do not have a relay for the DRL in my underhood fuse block. I removed the fuse in the dash fuse block and that disabled them with no adverse effects so fr. I would still like to redirect them to a different set of lights if someone knows how.

Thanks

I believe the DRL relay in your vehicle is located in what is called the "convenience center". It's under the driver's side instrument panel, attached to the firewall near and to the left of where the steering column goes through. It's a module that has some wiring plugged into it, and along the bottom, 3 relays.From left to right, the relays are fog lamps, drl, turn signal.

Did you ever figure out how to do option number one? I have some after market led lights and like to wire in to the daytime running lights
