Restore Full Functionality to Your Vehicle’s Electronics
Are you battling frustrating electrical problems in your GM vehicle? A faulty Body Control Module (BCM) is often the culprit behind a host of issues that can make your car feel unreliable and unpredictable. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your power windows and locks to the interior lights and security system. When it fails, it can cause a cascade of confusing symptoms.
From the Diagnostic Bay
We once had a customer with a Chevy Impala whose driver-side power window would only work intermittently. He had already replaced the window switch and the motor, with no luck. The interior lights would also flicker randomly. After checking the wiring, we hooked up our diagnostic scanner and found multiple communication error codes pointing to the BCM. Instead of a complex and expensive diagnostic path, the solution was a new, correctly programmed BCM. This single part restored not just the window, but also the lighting and key fob functions, saving the customer from further guesswork and unnecessary part replacements.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ The security system acting up, causing alarm or starting issues.
- ✔ Key fobs that suddenly stop working.
- ✔ Warning lights on the dashboard, such as the airbag or brake light, for no apparent reason.
- ✔ A complete no-start condition where the engine won’t crank.

Installation and Post-Install Notes
While installation is straightforward for many DIYers, some vehicles may require additional steps after the new BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic accessories not related to the engine, such as power windows, lights, security systems, door locks, and wipers.
What information do you need to program the BCM?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to program the module with the correct software and settings for your specific car or truck. Please provide it during or after checkout.
Is this part difficult to install?
The physical installation is typically simple, involving unplugging the old module and plugging in the new one. They are often located under the dash on the driver’s or passenger’s side. However, some vehicles may require post-installation relearn procedures as noted above.
Will this fix my specific electrical problem?
This module will correct issues directly caused by a failing BCM. If you’re experiencing symptoms like erratic lights, non-working power accessories, or security faults, a faulty BCM is a very likely cause.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module.
