Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your vehicle? Intermittent power windows, flickering lights, a security system that acts on its own, or a dashboard that resembles a Christmas tree 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 problems. This isn’t just an annoyance; a faulty BCM can affect vehicle security and even prevent it from starting. Stop chasing individual symptoms and address the root cause with our reliable, VIN-programmed BCM.
From the Diagnostic Bay
We once had a 2000 Silverado in the shop where the owner had spent hundreds of dollars replacing the driver’s side window motor twice and the master switch once. Still, the window would only work when it wanted to. After a quick scan, we saw communication fault codes pointing to the BCM. The internal circuits responsible for that specific window output were failing intermittently. We installed a VIN-programmed BCM, and the problem was solved instantly. It’s a classic case of treating the disease, not just the symptoms.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not working at all.
- ✔ The security system or alarm randomly activating or preventing the vehicle from starting (Security light on).
- ✔ Inconsistent or dead dashboard gauges and warning lights.
- ✔ Communication errors with diagnostic scan tools (U-codes).
- ✔ Wipers operating incorrectly or not parking in the correct position.
- ✔ Horn not working or sounding off unexpectedly.
The Plug-and-Play Solution: A Programmed 2000 Tahoe Body Control Module
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming programming required at a dealership. Our solution eliminates that step entirely. We take your vehicle’s VIN and program this module with the latest GM software updates specific to your truck or SUV before it ever leaves our facility. This ensures that when you receive it, it’s ready for a straightforward installation. This module is a direct replacement for part numbers 9385236, 19208539, and 9371990, guaranteeing compatibility and function.
Post-Installation Procedures
Because this module is pre-programmed, the installation is greatly simplified. However, in some vehicles, certain systems may need to be re-synchronized with the new BCM. These are simple procedures for any qualified technician with a professional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control system performance.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and interior accessories.
Do I need to get this module programmed by a dealer?
No. This is the key benefit of our service. You provide us with your vehicle’s VIN during checkout, and we program the module for you. It arrives ready for installation, saving you time and money.
Where is the BCM located on a 2000 Chevy Tahoe?
On the 2000 Tahoe and most similar GM trucks and SUVs from this era, the BCM is typically located under the driver’s side of the dashboard, to the left of the steering column.
What if my airbag light turns on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge or do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module.
