If you’re dealing with the classic, frustrating electrical gremlins in your 2001 GMC Safari or other compatible GM vehicle, you’ve come to the right place. Strange issues like flickering interior or exterior lights, power windows that have a mind of their own, erratic gauge behavior, or a security light that prevents your vehicle from starting are often traced back to one component: a failing Body Control Module (BCM). This isn’t just an inconvenience; it can be a major disruption to your daily life. As a technician, I’ve seen these exact symptoms hundreds of times, and replacing the BCM is often the definitive fix.
This isn’t just any replacement part. This is a direct-fit Body Control Module for part number 9385236, and we take the biggest hassle out of the repair for you. Before we ship it, we program the module to your vehicle’s specific VIN using the latest official GM software. This critical step ensures that the BCM communicates perfectly with your vehicle’s other systems right out of the box, saving you from a costly and time-consuming trip to the dealership for programming. Restore reliable function to your vehicle’s essential features with a solution designed for a perfect match.
Case Study: A Tricky Diagnosis
A customer brought in a 2000 Silverado 1500 with a parasitic battery drain that two other shops couldn’t solve. The battery would be dead every morning. They had already replaced the battery and alternator. After connecting my diagnostic tool, I noticed the BCM wasn’t going into ‘sleep’ mode, constantly drawing power even with the key off. This internal short in the module was also causing the dome light to flicker randomly. By installing a VIN-programmed BCM like this one, we solved the battery drain and the flickering light in one go. It’s a classic failure on these platforms, and this module is the correct fix.
Signs Your GM’s Body Control Module is Failing
A faulty BCM can cause a wide range of confusing symptoms. If your vehicle is experiencing any of the following, a failing BCM is a likely culprit:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft light stays illuminated, potentially causing a no-start condition.
- ✔ Erratic or non-functional instrument panel gauges.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Diagnostic trouble codes related to communication errors, such as U0140.
Your Straightforward BCM Installation Guide
Replacing the BCM is a manageable job for a DIYer with basic tools. Follow these steps for a successful installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to ensure all systems are powered down.
- Locate the BCM: On a 2001 GMC Safari, the BCM is typically located under the driver’s side of the dashboard, to the left of the steering column. For S10/Blazer/Sonoma models, it’s often behind the center dash area.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, windows, locks, wipers, etc.—to confirm the repair.
What to Expect After Installation
Because this module is pre-programmed, most vehicles will be ready to go. However, in some cases, minor follow-up procedures may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be done with a professional-level scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure proper brake light and traction control operation. This can also be performed with a capable scan tool.

Frequently Asked Questions
Do I need to program this 2001 GMC Safari BCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install with the latest GM software.
What does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, wipers, the security system, and the instrument cluster.
Is there a core charge for this part?
No, there is absolutely no core charge. You can keep your old module, which saves you the time and expense of shipping it back.
Where is the BCM located on my 2001 GMC Safari?
On the 2001 GMC Safari and similar vans/trucks (Astro, Silverado, Sierra, Tahoe, Yukon), the BCM is typically found under the dashboard on the driver’s side, near the steering column.
Why is my airbag light on after installing the new BCM?
This can happen because the new BCM needs to be electronically ‘introduced’ to the vehicle’s existing Airbag Control Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ using a professional scan tool will resolve this and turn off the light.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN for programming.
