Restore Full Function to Your GM SUV
Are you battling a frustrating series of electrical gremlins in your vehicle? Intermittent power windows, door locks that have a mind of their own, flickering interior lights, or a security system that won’t cooperate are all classic signs of a failing Body Control Module (BCM). This vital component is the central hub for your truck’s body electronics, and when it falters, it can make your daily drive a nightmare. This pre-programmed BCM is the definitive, hassle-free solution to get your vehicle back to perfect working order.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of confusing issues that may seem unrelated. If you’re experiencing any of the following, this module is the likely culprit:
- Power windows, mirrors, or door locks operating erratically or not at all.
- Interior dome lights or dashboard lights staying on or not turning on.
- The security or anti-theft system preventing the vehicle from starting.
- Erroneous warning messages on the instrument cluster.
- Communication failures with other onboard computer systems (often resulting in DTCs like U1000).

Expert Insight: The Domino Effect of a Failing BCM
As a technician for over 20 years, I’ve seen how a failing BCM can send owners on a wild goose chase. A customer once came in convinced his Trailblazer needed a new window motor, a door lock actuator, and had a parasitic battery drain. All three issues were happening at once. After some diagnostics, we traced it all back to one source: a faulty BCM that was sending corrupt signals across the data network. Replacing this single module fixed every single problem. It’s the nerve center of the vehicle’s body, and when it goes, it can create a confusing cascade of failures. This is why a quality, correctly programmed 2002-2004 Bravada BCM is so critical.
Important Post-Installation Steps
While this module is programmed for your vehicle, certain systems may require a recalibration procedure after installation to ensure they communicate correctly. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used 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 may be needed to ensure proper function of the brake lights and traction control system.
We provide this information to ensure a transparent and successful repair process. Always consult a factory service manual or a qualified technician if you are unsure about any step. Getting this right is key to restoring your vehicle’s full functionality. If you’re looking for a reliable fix for your SUV’s electrical woes, this programmed 2002-2004 Bravada BCM is the ideal solution.
Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready for installation.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to flash the BCM with the exact software and configuration for your vehicle’s specific options.
Will this fix my power windows and locks?
If the Body Control Module has been diagnosed as the source of the failure, then yes. The BCM is directly responsible for controlling these and many other electronic accessories, making it a very common solution for these types of problems.
What if my airbag light comes on after I install it?
This is a known possibility. The airbag system has a security link to the BCM. If the light appears, the ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-end scan tool to sync the modules and turn off the light.
Is this a difficult part to replace myself?
For someone with moderate mechanical skill, it is a manageable job. The BCM is typically located behind the fuse box on the driver’s side. However, due to the potential need for post-install relearn procedures, we always recommend consulting a service manual or having a qualified technician perform the work if you are not comfortable with vehicle electronics.
