2011 – 2013 Chevrolet Caprice Body Control Module (BCM) 20839063 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2011-2013 Chevrolet Caprice refusing to start, or the power windows acting up randomly during a rainy drive? As a seasoned mechanic who’s seen countless GM vehicles roll into the shop with these frustrating electrical gremlins, I know how a faulty Body Control Module can turn a reliable sedan into a headache. Questions like “Why won’t my Caprice’s lights work properly?” or “How do I fix intermittent door lock failures in my 2011 Chevy Caprice?” often point straight to BCM issues. This pre-programmed BCM, part number 20839063, arrives ready for your exact vehicle after you supply your VIN—we flash it with the latest GM updates for seamless integration. It’s compatible with a wide range of models, including Equinox 07-09, Impala 06-13, Tahoe 10, and more, covering equivalents like 10382479, 15093910, up to 95151084. By swapping in this module, you’ll clear persistent DTC codes related to body functions, restore smooth operation of accessories, and even enhance overall electrical reliability for daily commutes or long hauls. In my experience, this fix not only resolves symptoms but prevents cascading failures, like battery drain from malfunctioning relays, saving you from costly towing bills.
Key Features & Benefits

- Supports multiple compatible part numbers, making it a versatile solution for GM owners facing BCM failures across models like the Acadia or Express vans.
- Helps clear diagnostic trouble codes (DTCs) efficiently, improving features like remote start reliability and anti-theft system performance without extra hassle.
- Enhances vehicle safety by restoring proper control over airbags and braking signals, based on real cases where outdated modules caused warning lights to linger.
Common Issues & How This Fixes Them
In my two decades fixing GM cars, BCM problems in the 2011-2013 Chevrolet Caprice often stem from water intrusion, voltage spikes, or age-related component wear. One classic scenario: You’re cruising on the highway when suddenly the headlights flicker or fail—caused by a corrupted BCM not relaying signals properly, leading to unsafe night driving. This replacement module fixes it by recalibrating communication lines, ensuring consistent power distribution and clearing related DTCs like U0140 or B1370. Another frequent headache is intermittent no-start conditions, where the key fob won’t unlock doors or the engine cranks but doesn’t fire—often tied to theft deterrent malfunctions. Installing this pre-flashed BCM resolves that by syncing with your vehicle’s security protocols, and in cases of no-start post-install, a quick theft relearn (cycle the key from off to on three times, waiting 10 minutes each) gets things running without a scan tool. I’ve advised owners on this exact fix, preventing unnecessary battery replacements. Then there’s the erratic accessory behavior, like power seats or windows stalling mid-operation, which drains the battery over time. This BCM restores full functionality, improving electrical efficiency and even aiding in better fuel economy by optimizing idle controls. For Caprice police package models, it enhances towing reliability by stabilizing trailer light connections, avoiding roadside breakdowns. Overall, this isn’t just a part swap—it’s a targeted restoration that tackles root causes, drawing from patterns I’ve analyzed in diagnostic logs across similar GM platforms.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your 2011-2013 Caprice.
- Disconnect the negative battery cable to ensure safety and prevent electrical shorts during the process.
- Locate the BCM—typically in the center dash or under the steering column; refer to your service manual for exact positioning in your model.
- Remove the old module by unplugging connectors and unbolting it, then install the new one in reverse order, ensuring all plugs seat firmly.
- Reconnect the battery and perform any necessary relearns: If no-start occurs, initiate theft deterrent relearn by inserting the key, turning to ‘on’ for 10 minutes (three cycles if needed), then start the engine.
- Test all body functions like lights, locks, and windows; use a scan tool for final DTC clearance if warnings persist.
