Re: 2002 Honda Civic DRL module and relay location

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.
