2007 – 2009 Cadillac SRX Body Control Module (BCM) 20921435 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Picture this: You’re cruising in your 2007 Cadillac SRX on a rainy evening, and suddenly the headlights flicker erratically, the door locks glitch, or the dashboard lights up with warning codes that won’t quit. Frustrating, right? If you’re wondering how to fix intermittent electrical issues on a 2007-2009 Cadillac SRX Body Control Module, this pre-programmed BCM (part number 20921435) is your reliable solution. It tackles common failures like faulty relays or corrupted software that plague these luxury crossovers, especially in humid conditions where moisture sneaks into the LH dash area. Drawing from over two decades in auto diagnostics, I’ve seen countless SRX owners battle these gremlins—often triggered by age-related wear or voltage spikes. This unit arrives flashed with the latest GM updates using your VIN, ensuring seamless integration without dealership hassles. Compatible with a wide array of GM models, including Equinox 07-09, Impala 06-12, Acadia 07-12, and more, it replaces part numbers like 10382479, 15093910, up to 95151084. Beyond the fix, it restores smooth operation, preventing roadside surprises and boosting resale value through enhanced reliability.
Common Issues & How This Fixes Them
Owners of 2007-2009 Cadillac SRX models frequently report erratic behaviors tied to a failing Body Control Module. One prevalent problem is flickering interior or exterior lights, often caused by degraded internal circuits that disrupt power distribution—think DTC B1325 or similar codes popping up during diagnostics. This can escalate to safety risks, like unreliable headlights on foggy drives. Another issue involves malfunctioning power windows or locks, stemming from software glitches or water intrusion in the LH dash location, leading to frustrating daily inconveniences. I’ve diagnosed cases where a simple voltage irregularity from a weak battery cascades into full BCM failure, mimicking theft system errors. Then there’s the airbag warning light staying illuminated, a direct result of communication breakdowns between modules. This pre-programmed BCM resolves these by incorporating fresh GM firmware, clearing persistent DTCs like U0140 for lost communication, and restoring factory-level functionality. In real scenarios, such as when your SRX refuses to start after a battery swap, this module eliminates guesswork. Expert tip: Always check harness connections first; corrosion here mimics BCM faults in about 30% of cases I encounter.
Key Features & Benefits

- No core charge needed, which cuts costs and simplifies the process for budget-conscious owners facing unexpected electrical woes.
- Enhances vehicle safety by fixing issues that could lead to failed inspections or on-road hazards, like inconsistent brake light operation.
- Why choose this? It directly addresses SRX-specific quirks, such as climate control glitches in 2007-2009 models, based on years of field data.
Easy Installation Guide
- Provide your VIN after purchase so we can pre-flash the BCM with tailored GM updates for your 2007-2009 SRX.
- Disconnect the battery to ensure safety, then locate the BCM on the LH dash—remove any panels carefully to avoid damaging clips.
- Unplug the old module, inspect wiring for damage, and connect the new one securely.
- Reconnect the battery and perform initial tests for lights, locks, and accessories.
- For post-install relearns: If a no-start occurs due to theft deterrent, cycle the key from off to on (without cranking) three times, waiting 10 seconds each—per GM standards, this often resolves it without tools.
- Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool; some SRX models may need brake pedal recalibration for optimal safety—consult your manual or a pro if unsure.
