Damn...I have the same problem...i was thinking of just pulling the DRL fuses.
Hey I know what to do now. The sound is coming from behind the glove box. So I opened it and try to see where te sound is coming from and I think I found the problem.
After you remove the glove box, look all the way to your left. You will see two relays ("cube" like object), one black and one gray. The one making the sound is the gray one. You can pull it out (pull it vertically, to the sky). It's just like a plug.
The relay is MITSUBA JAPAN RC-5102 12v 1T 2XG.
So RC-5102 relay is the item to replace.
Now if you know where I can get it online (ship to Canada) or how much is it from dealer, let me know.
It was just afew days ago I just got frustrated and just pulled the interior DRL fuse itself from my 2001 Civic. Cured the problem for my needs; no sound, no flickering DRL dash light.
I couldn't really care if my DRL's are on or not in a 10yr old car. At early dawn, dusk and at night is when I will actually need to turn on my main lights physically anyway.
had the same problem and the fix was one of the wires that's coming from the connector that connect to the combination switch (headlight switch) was at the wrong pin. you got to get a schematic and match it to your wiring
I started to get this buzzing over the last few days, and my high beam passendger side light doesnt come on anymore, I pulled the module out today and had a look, 10 solder joints all cracked, it amazes me that such a common problem doesnt have a recall.
Anyway ill be attempting to redo those joints tonight.
