What does your owners manual have to say about them?

If push comes to shove, you could always remove a battery cable.

My money is on the the owners manual.

Good Luck!

Probably nothing. This is a service problem and not a normal use
problem. If he has a service manual he may find an answer.

I'd pull a fuse and not lose all the radio information and whatever
else is lost. Pulling a cable on today's care can be a real PITA when
you put it back.

Not mine. I'd bet on the service manual. Could be a sticking relay.

DRL module may be bad.
As Ed said, pull the fuse on the DRL module.

And then throw it away.

BCM controls DRL. And if you pull the DRL relay I think the headlamps
don't work either, it's designed to not be easily disabled. But pulling
the relay while parked overnight will keep the battery from dying until
it can be diagnosed and repaired.

Interesting. Had not thought of the BCM.

the wiring diagrams for the headlights and DRL on GM can make you dizzy
in a hurry, but the "theory of operation" section explains it.
