buzzing sound from the glove compartment ....if I dont turn on my headlights
 

I have a honda civic 2001, I normally start the car and put the vehicle in
drive and the daytime running lights initate.Now , when I start the car put
the vehicle in drive then the drl lights on dashboard goes on and off and
also there is a buzzing sound originated from the dashboard, to stop both
from happening I need to turn on my headlights and everything is fine.I took
the glove compartment out and there is two switches for the daytime running
lights,the buzzing is coming from the one of the two switches.I was told
that there is a daytime running light relay under the dashboard by the
drivers side.My question is what is causing the buzzing..i was told that it
was the relay located under the drivers side dashboard. The other question
is if I replace the daytime running light relay could I use a 2001-2006
relay or should I have to use a 2001 one..thanks to everyone's
response..thanks
