There is no DRL module .
Daytime Running Lamps (DRL)
The DRL are a function of the front turn signal lamps. The DRL will operate when the ignition switch is in the RUN position, the gear selector is not in the PARK position, and the headlamp switch is in the OFF position. When the BCM receives these signals it will signal the turn/hazard flasher module to turn on the DRL by grounding the DRL low control signal. The turn/hazard flasher module supplies voltage to the DRL on the right and left DRL/turn supply voltage circuits. If a front turn signal lamp is inoperative the DRL will not operate.
The DRL can be deactivated by turning the headlamp switch to the DRL OFF position while the DRL are operating. The DRL defeat position of the headlamp switch is a momentary ground signal to the BCM to command the DRL function ON or OFF. After each key cycle the BCM will default to the DRL ON function.

What makes you think it needs replacement? It lives in a very clean environment and rarely fails. Low refrigerant, on the other hand, would be picked up by the low pressure switch, and it would shut down the system to prevent EXPENSIVE damage... Great design, I think.
Replacement of the low pressure switch would require recovery of refrigerant, evacualtion of the system, and recharge, at minimum.
this job is best left to a qualified shop, as you risk serious personal injury.
