Where is the DRL module in a 1999 Chevy Venture?

The Daytime Running Lamps (DRL) module in a 1999 Chevy Venture isn't a separate, easily identifiable module like a computer or fuse box. The DRL function is integrated into the vehicle's Body Control Module (BCM). The BCM is usually located under the dashboard, often on the driver's side. However, the exact location can vary slightly depending on trim level and options.

To find it, you'll likely need to:

1. Consult your owner's manual: This is the best place to start. It might have a diagram showing the BCM location.

2. Check online forums: Searching for "1999 Chevy Venture BCM location" on forums like ChevyTalk or similar sites might reveal pictures and descriptions from other owners.

3. Use a wiring diagram: A wiring diagram specific to your year and model Venture will show the circuits related to the DRLs and their connection to the BCM. This is the most definitive way to trace the system but requires some electrical knowledge.

Important Note: Working with the BCM can be complicated and potentially risky. If you're not comfortable with automotive electrical systems, it's best to take your Venture to a qualified mechanic for diagnosis and repair of DRL issues. Improperly working on the BCM can lead to further electrical problems.
