The DRL module is right under the dashboard to the right of the steering wheel. It is a small metal box similar to a PC's heat sink... It is very difficult to remove. I believe the easiest way to remove it is by bending the metal tabs that hold it into place. This is not the module , it is the diode, as per wiring diagram, it is a double diode with heat sink, it is removable as stated and unpluging will disable drl,s It has only two wires one orange and one yellow. The module is a small circuit board that plugged in to another component and has 8 tabs/connectors about 2 inch square and on half inch thick. I cant find it either.
The drl relay is located in the back of the glove compartment.
The DRL Module is located at the LH Rocker Panel left of the brake, under and just below the dash. The DRL Module and the DRL Relay are side-by-side.
A ( Daytime Running Light ) module
A DRL module controls the daylight running lights found on many newer and Canadian cars.
The drl module on chevy epica 2004 is back to the data link connector
The DRL control module is located under the steering column on the left hand side!
Find and disable the DRL module.
Under the dash on the left side.
Under the dash directly above the gas pedal, find the black relay/module that has an upsidedown white label that says "Hamsar". Disconnect the wiring harness that leads to this module. POOF!! no more DRL's. As far as I can tell this affects the DRL's and nothing else.
You probably need a new DRL module and/or DRL relay.In some instances the module is fixible.
DRL modules are like fuses...they are inexpensive, & usually replaced, not repaired.
