Restore Your SAAB’s Electrical System with a Plug-and-Play Solution
If you’re dealing with baffling electrical issues in your 2005 SAAB 9-7X or a related GM SUV, you know the frustration. Flickering lights, malfunctioning power windows and locks, a radio with a mind of its own, or worse—a vehicle that won’t start. These aren’t just annoyances; they’re 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 fails, it can cause chaos. This isn’t just a replacement part; it’s a direct, reliable fix. We take your vehicle’s VIN and program this module with the latest GM software before it even ships. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
A Technician’s Notebook: The GMT360 Platform Gremlin
I’ve seen hundreds of these GMT360 platform vehicles (Trailblazer, Envoy, 9-7X, etc.) roll into my bay with the strangest symptoms. A customer once had a 2005 Envoy where the rear wiper would turn on every time he used the left turn signal. Another had a Trailblazer that would randomly unlock its doors while driving. In over 90% of these cases, the culprit was a failing BCM, often due to moisture intrusion or simple electronic fatigue. Swapping in a pre-programmed module like this one is the most efficient repair. It takes the guesswork out and provides a stable, lasting solution that restores all functions to factory-spec performance. It’s the fix I recommend to my own customers.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior.
- ✔ The security light stays on, preventing the engine from starting.
- ✔ The radio or instrument cluster powers on and off randomly.
- ✔ False warning lights on the dashboard, such as the airbag light.
- ✔ Communication error codes with other modules (U-codes).
- ✔ Complete loss of power to various accessories.
Your Direct-Fit Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most of these models, including the 2005 SAAB 9-7X, the BCM is part of the front fuse box assembly, typically located under the rear seat on the driver’s side. Consult your service manual to confirm the exact location.
- ✔ Remove the Old Module: Carefully disconnect all electrical connectors attached to the BCM. Note their orientation. Unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM securely in place. Reconnect all electrical connectors firmly, ensuring they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Final Checks: Turn the key to the ‘ON’ position and verify that power windows, locks, lights, and other accessories are functioning correctly. Refer to the post-installation notes below for any additional steps that may be required.
Important Post-Installation Procedures
While this module is programmed to your VIN for a straightforward installation, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated 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 system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Is this BCM truly plug-and-play?
It is pre-programmed to your vehicle’s VIN, which handles 99% of the setup. In some cases, as noted above, minor relearn procedures like an airbag sync or brake pedal sensor relearn may be needed with a scan tool.
What information do you need from me?
After you place your order, we will need your 17-digit Vehicle Identification Number (VIN) to program the module correctly before shipping.
Will this fix my no-start problem?
If your no-start is caused by the BCM’s control over the vehicle’s security system (Passlock/Passkey), then yes, this programmed module should resolve the issue.
What if my original part number is not 9352135?
This module is a direct replacement for several part numbers, including 15122670, 15065293, 15114669, and 15191621. As long as your vehicle is on the compatibility list, this part will work.
