Is Your 2013-2014 Express Van Experiencing Strange Electrical Issues?
The Body Control Module (BCM) is the central nervous system for your vehicle’s electronic accessories. It doesn’t control the engine, but it manages nearly everything else—from your power windows and door locks to your interior lights, security system, and instrument cluster. When the BCM starts to fail, it can create a cascade of confusing and frustrating problems that seem unrelated. One moment your turn signal might not work, and the next, the radio won’t turn off. If you’re tired of chasing electrical gremlins, a faulty BCM is often the culprit.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on or not turning on).
- ✔ The vehicle’s security system malfunctioning or preventing the engine from starting.
- ✔ Instrument cluster gauges flickering, working intermittently, or displaying incorrect information.
- ✔ The horn sounding randomly or not working at all.
- ✔ Wipers operating on their own or not responding to the switch.
- ✔ Key fob not being recognized or having a very short range.
A Pre-Programmed Solution for Your Express 1500 Body Control Module
Replacing a BCM isn’t just a matter of swapping parts. A new module must be programmed specifically to your vehicle’s Vehicle Identification Number (VIN) and its unique set of options. Dealerships charge a premium for this service. We eliminate that hassle and expense. When you order this Express 1500 BCM, we flash it with the latest GM software updates using the VIN you provide. This means the module arrives at your door ready for installation, saving you a trip to the dealer and costly programming fees.
This is a direct-fit replacement for part numbers 22820314 and 22915542, ensuring seamless integration with your vehicle’s existing systems. Best of all, there is no core charge. You can keep your original module without the hassle of shipping it back.
Installation and Required Procedures
Physically installing the BCM is typically straightforward, involving basic hand tools to access its location (often in the center dash or driver’s side dash area). However, after the new module is connected, a couple of additional electronic procedures may be necessary to ensure all systems communicate correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and must be performed with a professional-grade diagnostic scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed. This ensures the brake lights and traction control system function as intended.
Disclaimer: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for detailed guidance.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready to be installed.
Where do I find my VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
What tools are required for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a high-level, bi-directional diagnostic scan tool, such as a GM Tech 2 or equivalent professional equipment. Most basic OBD-II code readers cannot perform these functions.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your original BCM.
Will this fix my check engine light?
The BCM typically does not control engine functions. If your primary issue is a check engine light, you should diagnose the powertrain codes separately. This module resolves issues with body electronics like lights, locks, windows, and security systems.
