I don't know where for sure, but one possible location is under the dash on
the driver's side. Are you trying to replace it, and if so, why?

You have three items that concern the DRLs. They are all under the dash to
the left of the steering column:
1) Low-beam cut relay
2) DRL Relay
3) DRL Control Unit (bigger than the others)

Are your DRLs no longer working? That's usually the low-beam cut relay.
Look for a relay with the wires RED/BLK, RED/YEL, RED/WHT, RED/BLU. It's
joined together with the DRL relay, which is the same size but has
different wire colors.

There are input tests you can do to the relays to confirm functionality.

my car seems to have an electrical problem. I get a buzzing noise when I
start the car. The daylight driving light does not work, but when I turn on
the headlights the buzzing noise goes away. I changed the bulb and the
noise has not gone way. Also when the headlights are off and the buzzing
sound is buzzing the DRL light is on in my dash. I am assuming it is the
DRL module or relay. I'm not sure if I shoudl tackle this myself or take it
to a shop to get fixed. I am hearing that it is an easy fix, but I don't
even know where these are located.

Do i need to take the dash off to get to these or are they somewhat easily
accessible?

Accessible from under the dash. Usually you need to remove the plastic knee
bolster under the steering column ( a few bolts and clips). Get under there
with a flashlight and look for yourself.

Believe it or not, I think the culprit here is a failing alternator. I had
very similar symptoms with my 2004 Civic LX recently. But instead of a
buzz, it was a fast tick; and it went away with the headlights turned on.

If it is the alternator, I strongly suggest to get the battery checked at
the same time especially if it is the original.

Hi guys. I recently acquired a used '01 Civic, and I think that car
suffers from a series of very similar symptoms...
- DRL lit on dashboard
- DRL sign turns off when headlights are switched on (whether high or
low beams)
- Blown DRL 10A fuse
- Upon DRL fuse replacement, noise coming from the glove compartment
area
- Changed gray DRL relay (RC-5102); no change, same buzzing noise
- Took off the DRL module from under the bottom left of the dash. Took
it apart to inspect all solderings. No clear evidence of a cold one,
but nonetheless re-soldered a few that didn't look as good as the
others. Put everything back into place: same exact scenario.
- Decided to inspect the right headlight bulb: to my surprise, the
high beam wire was cut and the bulb itself was cracked in its forward
portion. Went back to Canadian Tire (for the 3rd time today!) and
bought a new bulb. Replaced it, and I still have the exact same
problem!!

I did notice though that the high beam is definitely linked to this
problem, since even when the headlights are off, simply having the
high beams on (by pressing the steering-mounted lever) turns off both
the buzzing sound and DRL sign. Now that I've exhausted all of what I
could try today, I'm turning to you guys; maybe someone could shed
some light into this (no pun intended!!) Thanks in advance.

Low cut relay.

Did you even read my post that you directly responded to? If your fixes did
not cure the problem, it's likely the alternator. It seems to be a fairly
common problem on this version of Civic.

What part of the alternator I wonder? Do these have a removable brush
pack/regulator? The brushes are a common wear item, occasionally one or
more of the 6 diodes will fail, usually all 6 are part of one assembly.

I don't know which part(s) specifically. When the same thing happened with
my 2004 Civic, the whole alternator was replaced under warranty. In fact,
the diagnosis as indicated on the invoice said "internal failure". I don't
know if worn brushes would have been the cause, especially this soon.

Yeah that would be unlikely, my guess is one or more of the diodes
failed and the ripple current went through the roof. Some electronics
deal with that a lot better than others.

Same as Doobielicious.. so I`m interested in this solution.
Anyone has the electrical wiring diagram ?

thanks
