Are you battling frustrating electrical problems in your GMC Sierra, Chevrolet Silverado, or other GM truck? Flickering lights, unresponsive power windows, a malfunctioning security system, or random warning lights are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of perplexing issues. This genuine GM BCM, interchangeable with part number 15263363, is the definitive solution to restore your vehicle’s performance and reliability.
Is Your GM Truck’s BCM Failing?
A faulty BCM can manifest in numerous ways, often making diagnosis difficult. If your vehicle is experiencing any of the following, a replacement module is likely the answer:
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ Malfunctioning HVAC controls or a blower motor that works intermittently.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ Security system issues, including no-start conditions or random alarm activation.
- ✔ Inconsistent windshield wiper operation.
- ✔ A dashboard lit up with multiple, seemingly unrelated warning lights.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
