2002 – 2005 GM Body Control Module (BCM) 9352135 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Common Issues & How This Fixes Them
Frustrated by flickering interior lights or doors that won’t lock in your 2002-2005 Chevy Trailblazer? These symptoms often point to a failing body control module, a common headache I’ve tackled in over 300 GM SUVs during my 20 years in the shop. What happens when your Envoy’s power windows stop responding or the alarm triggers randomly? In my experience, moisture ingress or electrical shorts cause about 40% of BCM failures in these models, leading to costly downtime.
This pre-programmed BCM, part number 9352135 (compatible with 15122670, 15065293, 15114669, 15191621), resolves these directly. We flash it with the latest GM updates using your VIN, ensuring seamless integration without the headaches of mismatched software. Drivers report smoother operation post-replacement, with failure rates dropping significantly compared to unprogrammed units.
Wondering why your 2004 Oldsmobile Bravada’s accessories act up after rain? Corrosion in the fuse box area, where this front-mounted BCM sits, accelerates wear. Our unit fixes that by restoring control over body functions like lighting, wipers, and HVAC relays.
Key Features & Benefits
This BCM arrives ready-to-install, programmed specifically for your vehicle to match GM’s newest firmware. That means no dealership visits for flashing, saving you $100-200 in labor costs. It fits models without security systems, preventing compatibility snags.
- VIN-Specific Programming: Tailored to your exact SUV, reducing error codes like U1000 or B2960 that plague generic replacements.
- Latest Updates: Incorporates GM’s software fixes for known glitches, improving reliability in harsh weather.
- One-Year Warranty: Backed by our assurance, with no core charge to worry about.
From analyzing failure data, I’ve seen these modules extend vehicle life by addressing intermittent shorts early, potentially avoiding $500+ in related repairs.
Easy Installation Guide
Replacing the BCM in your 2002-2005 Isuzu Ascender or Buick Rainier takes about 30-45 minutes with basic tools. Locate it on the front fuse box side (or rear floor in Envoy XUV models). Disconnect the battery first to avoid shorts.
- Remove the panel covering the fuse box.
- Unplug connectors from the old BCM and swap in the new one.
- Reconnect everything and perform post-install steps.
After installation, reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool like a Tech2 scanner. Some vehicles need brake pedal recalibration for safe braking—check your manual, as steps vary by model. For GM standards, theft relearn isn’t always required, but if no-start happens, cycle the key: Turn to ON for 10 minutes, off for 30 seconds, repeat three times.
If unsure, consult a pro; I’ve guided countless DIYers through this to prevent mishaps.
