The daytime running light (DRL) module isn't a separate, easily identifiable component in a 2002 Dodge Caravan like it might be in some other vehicles. The DRL functionality is integrated into the body control module (BCM). The BCM controls various electrical functions of the vehicle, and the DRLs are one of them. There's no single "DRL module" to replace or access directly.
Therefore, you won't find a specific DRL module to locate. If you're having issues with your DRLs, the problem likely lies within the BCM itself, the wiring harness, or a related switch/fuse. A mechanic or qualified automotive electrician would need to diagnose the problem using diagnostic tools to determine the source of the malfunction.
