Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your vehicle? Intermittent power windows, flickering interior lights, a security system that acts on its own, or warning lights that won’t go away are all 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 wide range of confusing and unpredictable problems. This replacement Body Control Module, compatible with part numbers 9371990, 19208539, and 9385236, is the definitive solution to get your truck or SUV back in reliable working order.
Unlike a standard replacement part from a dealer or salvage yard, this BCM arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We handle the complex flashing process for you, loading the latest GM software updates before we ship. This means no expensive trips to the dealership for programming, saving you time, money, and hassle. The result is a streamlined installation process that restores your vehicle’s original functionality and performance.
From the Diagnostic Bay
We had a 2000 Silverado 1500 roll into the shop with a list of bizarre symptoms the owner called ‘ghostly gremlins.’ The radio would lose its presets, the dome light would randomly turn on while driving, and the power locks only worked when they felt like it. A scan tool showed multiple ‘Loss of Communication’ codes with various modules. After confirming all the main power and ground connections were solid, our diagnostics pointed directly to a failing BCM. We installed one of our VIN-programmed modules, and in less than an hour, every single electrical issue was gone. The customer was thrilled to have his reliable truck back, free of the frustrating ghosts in the machine.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ Malfunctioning security system or keyless entry.
- ✔ Instrument cluster gauges behaving incorrectly or warning lights staying illuminated.
- ✔ Issues with the radio, climate control, or other interior accessories.
- ✔ A ‘No Communication’ error when scanning with a diagnostic tool.
- ✔ Parasitic battery drain that kills your battery overnight.

Installation and Post-Install Procedures
This BCM is located on the left-hand (driver’s) side of the dash in most compatible models like the Tahoe, Yukon, and Silverado, or in the center dash for models like the S10 and Blazer. Installation is a direct swap. While our VIN programming makes this a plug-and-play repair for most functions, some vehicles may require additional relearn procedures after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on 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 module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific guidance. There is no core charge for this part, so you can keep your original module.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and instrument cluster warnings.
Is this module difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. It involves removing a few dash panels to access and swap the module. Since we pre-program it, the most difficult part of the job is already done for you.
Do I need to program this BCM?
No. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready to be installed, saving you a trip to the dealership.
How do I provide my vehicle’s VIN?
You can provide your 17-digit VIN during the checkout process or send it to us in a message after placing your order. We cannot ship your part until we have this information.
What if the airbag light comes on after I install it?
This can happen on some vehicles. It means the new BCM needs to be electronically introduced to the airbag module. A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Does this part have a core charge?
No, there is no core charge. You are not required to send your old BCM back to us.
