Are you battling frustrating electrical gremlins in your Oldsmobile Bravada, Chevy S10/Blazer, or GMC Sierra/Sonoma? Intermittent power windows, flickering lights, a malfunctioning security system, or door locks with a mind of their own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and unpredictable issues. This isn’t just an annoyance; it can affect the safety and reliability of your vehicle. Don’t let a faulty module keep you off the road. We have the direct, reliable solution.
This is a replacement Body Control Module, part number 9366801, which is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical programming step ensures that the module communicates perfectly with your truck’s other systems right out of the box. We install the latest, most stable software updates from GM, which can resolve issues that were present even in the original factory programming. By providing us with your VIN during checkout, you receive a component that is prepared for a straightforward installation, saving you a costly trip to the dealership for programming.
Diagnosing a Faulty 1998 Bravada BCM
A failing BCM can be tricky to diagnose because its symptoms often mimic other problems. You might suspect a bad window motor or a faulty switch, but if multiple, unrelated electrical components are acting up, the BCM is the most likely culprit. It acts as the central hub, receiving inputs from switches (like your power window switch) and sending commands to motors and lights. When its internal circuits or logic fail, those commands become erratic or stop altogether.
Common Symptoms of BCM Failure
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system or anti-theft light flashing, preventing the engine from starting.
- ✔ The radio or climate control display behaving strangely.
- ✔ Gauges on the instrument cluster working intermittently or providing incorrect readings.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
- ✔ False warning lights appearing on the dashboard.
A Simple Installation Process
This BCM is designed for a direct fit. Once you receive your VIN-programmed module, the physical installation is typically straightforward. The BCM is usually located under the dashboard. While the process is simple, it’s important to follow proper procedures, starting with disconnecting the vehicle’s battery. After swapping the modules and reconnecting the battery, you may need to perform a couple of simple relearn procedures. In some cases, if the airbag light appears, a ‘Setup SDM Primary Key in BCM’ procedure is required using a professional scan tool to sync the new BCM with the airbag system. Additionally, a Brake Pedal Position Relearn might be necessary to ensure proper brake light and traction control function. These procedures are often straightforward for a qualified technician.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors most of the non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and more.
Do I need to program this BCM?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN at checkout, and we will flash the module with the latest GM software specific to your truck. This makes installation much simpler.
Where is the BCM located on my vehicle?
On most compatible models like the 1998 Bravada, S10, and Blazer, the BCM is located behind the center of the dashboard, often near the glove box area. On Silverado, Sierra, and Astro/Safari models, it’s typically found on the driver’s side, behind the lower dash panel (LH dash).
What is a ‘core charge’?
A core charge is a deposit that is returned to you when you send back your old, failed part. This BCM has no core charge, so you can keep your original module without any extra fees.
Will I need special tools for installation?
Basic hand tools are usually sufficient for the physical replacement. However, as noted in our post-install procedures, a professional diagnostic scan tool may be required for specific relearn procedures, such as syncing the airbag system (SDM key setup) if the airbag light comes on after installation.
How do I provide my VIN?
You can enter your 17-digit VIN in the designated field during the checkout process. Please double-check it for accuracy, as this number is critical for correct programming.
