Where is daytime running light module on 1994 dodge ram?

There isn't a dedicated "daytime running light (DRL) module" in the way many later vehicles have. 1994 Dodge Rams didn't have factory-installed DRLs in the modern sense. They might have had a system that dimmed the headlights slightly, or used a different strategy entirely (possibly none at all depending on the trim level and regional regulations).

To find out how your 1994 Dodge Ram handles daytime lighting, you'll need to:

1. Consult your owner's manual: This is the best place to start. It will specify how the lights are supposed to function.

2. Inspect the wiring harness: This is a more involved task and requires some electrical knowledge. You would need to trace the wiring from the headlight switch and potentially the dimmer switch to see if there's any specific circuit dedicated to reducing headlight intensity during the day. This is not recommended unless you have experience with automotive electrical systems.

3. Check the headlight switch: Some older vehicles used the headlight switch in a way that automatically dimmed the headlights slightly during the day.

In short, the absence of a dedicated DRL module is typical for vehicles of that era. The system is likely integrated into the existing headlight circuitry rather than a separate module.
