    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.

  5. 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.
