Where is the daytime running lights module located on a 2003 dodge ram 1500 4.7?

There isn't a separate "daytime running lights module" in the way some vehicles have for more complex systems. On a 2003 Dodge Ram 1500 with the 4.7L engine, the daytime running lights (DRLs) functionality is integrated into the body control module (BCM). The BCM is the central computer controlling many electrical functions.

Therefore, you won't find a specific DRL module. If you're having DRL issues, the problem likely lies within the BCM itself, the wiring harness, or a related switch/sensor. The BCM is usually located under the dash, often behind the glove box or on the driver's side. However, accessing it requires some disassembly and you might need a repair manual specific to your year and model to locate it precisely and avoid causing further damage.
