The wiper pulse module on a 2004 Chevy Silverado isn't a separate, easily identifiable module like a fuse box. The wiper motor control is integrated into the
Body Control Module (BCM). The BCM is usually located under the dashboard, often on the driver's side, but its exact location can vary slightly depending on the trim level and options. You'll likely need to consult a wiring diagram specific to your truck's year and model to pinpoint it.
Instead of looking for a "wiper pulse module," you should focus on finding the BCM. If you're having wiper problems, replacing the BCM is usually the last resort after checking simpler things like fuses, wiring, and the wiper motor itself. A qualified mechanic will have the tools and knowledge to properly diagnose the issue before replacing any expensive modules.
