Restore Your Saturn’s Electrical System with a Plug-and-Play BCM
Are you battling a storm of bizarre electrical problems in your Saturn Outlook? Flickering lights, malfunctioning power windows, a security system that acts up, or even a frustrating no-start condition? As a technician with over two decades of diagnostic experience, I’ve seen these exact issues countless times. The culprit is almost always a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. When it goes, it can feel like your car has a mind of its own. This isn’t just an inconvenience; it can compromise your vehicle’s safety and reliability.
We offer a dependable and straightforward solution: a replacement Body Control Module, part number 20935349, specifically for your vehicle. The biggest hurdle in this repair is typically the programming, which requires expensive dealership tools. We eliminate that problem entirely. Simply provide your vehicle’s VIN during checkout, and we will flash this module with the latest official GM software for your specific 2007-2010 Outlook BCM. It arrives at your door ready for installation, saving you a costly trip to the dealer and getting you back on the road faster.
Case Study: A Tricky Diagnosis
A customer’s 2008 Saturn Outlook came into the shop last month 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 multimeter, I confirmed a significant draw. By pulling fuses one by one, I isolated the circuit to the BCM. Even with the key off, the module wasn’t letting certain interior light and accessory circuits go to ‘sleep.’ This internal short was slowly killing the battery. Swapping in a pre-programmed 2007-2010 Outlook BCM not only fixed the battery drain but also resolved a complaint of intermittent power lock failure the owner had forgotten to mention. It’s a perfect example of how one faulty module can create multiple, seemingly unrelated symptoms.
Common Signs of a Failing BCM
If your vehicle is showing these symptoms, a faulty Body Control Module is the likely cause. Don’t let these issues leave you stranded.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights (like the security or airbag light) staying on.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ Key fob not responding or intermittent remote start issues.
- ✔ Engine cranks but won’t start due to a security system fault (anti-theft).
- ✔ Unexplained battery drain that kills the battery overnight.
A Straightforward Guide to Installation
Installing your new BCM is manageable for a DIYer with basic tools. The key is our pre-programming service, which handles the most complex step for you.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the 2007-2010 Saturn Outlook, the Body Control Module is typically located in the center dash area. You may need to remove lower dash panels for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. 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 and securely reconnect all electrical harnesses. Ensure they click into place.
- Reconnect the Battery: Reattach the negative battery terminal and tighten it securely.
- Critical Post-Installation Procedures: After installation, two key procedures are often required. First, the ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible diagnostic tool to clear the airbag warning light. Second, some vehicles may need a brake pedal position sensor recalibration. If you are not equipped to perform these steps, a local qualified technician can complete them for you.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your vehicle.
Is this a simple plug-and-play installation?
For the most part, yes. Our VIN programming service handles the software side, so you won’t need a GM Tech 2 scanner for initial setup. However, as noted, you may need a diagnostic tool to perform the ‘Setup SDM Primary Key’ for the airbag system and a brake pedal recalibration. This is standard for any BCM replacement.
Will this fix my specific electrical problem?
This 2007-2010 Outlook BCM is the correct solution for issues caused by a faulty module. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
What if I install it and my problem doesn’t go away?
If the issue persists after installation, it suggests the problem may lie elsewhere in the vehicle’s electrical system, such as a wiring short, a faulty ground, or another component on the same circuit. Our pre-tested modules are highly reliable, but complex electrical issues sometimes involve more than one faulty part.
Does this module come with a warranty?
Yes, all of our electronic modules come with a warranty that covers defects in the part itself. Please refer to our warranty policy page for complete details and duration.
