Restore Your Saturn’s Electrical System and Drive with Confidence
Are you dealing with baffling electrical issues in your 2007-2010 Saturn Outlook? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or even a vehicle that refuses to start can all point to one culprit: 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 create frustrating and unpredictable problems. This isn’t just an inconvenience; it’s a matter of reliability and safety.
This replacement Body Control Module, part number 20935349, is the definitive solution to get your vehicle back to perfect working order. We take the guesswork and high costs out of the equation. Forget expensive dealership appointments and towing fees. Simply provide us with your vehicle’s VIN at checkout, and our expert technicians will program this module with the latest GM software specific to your Saturn Outlook. It arrives at your door ready for installation, making this a straightforward repair for a seasoned DIYer or a time-saving solution for any professional mechanic.
From the Diagnostic Bay: The Case of the Haunted Outlook
I remember a 2008 Saturn Outlook that came into my shop last winter. The owner was at her wit’s end. The interior lights would pulse randomly, the radio would shut off, and twice it left her stranded with a no-start condition. Initial checks on the battery and alternator were fine. A scan revealed a dozen communication error codes (U-codes) pointing to a network failure. This is a classic sign of a BCM breakdown. The internal logic fails, and it starts sending corrupt data across the vehicle’s network. After confirming power and ground to the original BCM were solid, we knew it was the module itself. We installed one of our pre-programmed units, and within an hour, every single electrical gremlin was gone. It’s a satisfying fix that brings a vehicle back from the brink.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ Erratic behavior from the instrument cluster gauges or warning lights.
- ✔ Complete loss of communication, often resulting in diagnostic trouble codes like U0140.
- ✔ Unexplained battery drain that kills your battery overnight.
- ✔ Wipers or horn activating on their own or not working at all.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes before beginning.
- ✔ Locate the BCM: On the 2007-2010 Saturn Outlook, the BCM is typically located in the center dash area, often accessible by removing the glove box or lower dash panels.
- ✔ 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 plug in all electrical connectors. You should hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, etc.—to ensure proper operation.
- ✔ Perform Relearns (If Needed): In some cases, post-install procedures like an Airbag System Sync or Brake Pedal Position Relearn may be necessary. This typically requires a professional scan tool. See our FAQ for more details.

Frequently Asked Questions
What is the ‘Cloning Service’ and how does it work?
Our service involves programming this replacement BCM with your vehicle’s specific data using the VIN you provide. This ensures it communicates perfectly with your car’s other modules, like the engine computer and key fobs, making installation much simpler than buying a blank module from a dealer.
Do I need to send my original BCM to you?
No, we do not require your original module. We program the replacement unit using your VIN. Per our policy, if you do send your original module for data transfer, it is always returned to you along with the newly programmed replacement.
Will I need to program my keys after installation?
In most cases, because we program the module to your VIN, your existing keys should work without any additional programming. However, on rare occasions for certain GM security systems, a key relearn procedure may be necessary. This can typically be done without special tools.
What if my airbag light comes on after I install the BCM?
This can happen if the new BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a bi-directional scan tool to resolve this. This is only required if the light appears post-installation.
Is this a difficult part for a DIYer to replace?
For someone with basic mechanical skills, this is a very manageable job. The primary challenge is accessing the module, which may require removing some interior trim panels. Since the module comes programmed, the electrical part is simply plug-and-play.
