Are you tired of dealing with bizarre electrical issues in your GM truck or SUV? Power windows with a mind of their own, intermittent radio or A/C controls, or a security light that keeps you from starting your vehicle? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). For years, the only solution was an expensive trip to the dealership for a new module and costly programming. Not anymore.
This is a direct-fit replacement Body Control Module, specifically for a wide range of 1998-2000 GM vehicles. The best part? We handle the programming for you. Before we ship the part, we flash it with the latest GM software updates, perfectly matched to your vehicle using the VIN you provide. This eliminates the need for dealer-specific tools, saving you time, hassle, and hundreds of dollars. You get a reliable, plug-and-play solution that restores the functionality you depend on every day.
Is Your Truck Showing These Symptoms?
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior lights staying on or not working at all.
- ✔ The security or anti-theft light is illuminated, causing a no-start condition.
- ✔ Radio, climate control, or other dash functions work intermittently.
- ✔ False warning lights on the instrument cluster (e.g., airbag, brake).
- ✔ Communication loss codes with other modules, such as U-series codes.
A Technician’s Notebook
I remember a 2000 Sierra 1500 that came into the shop with a complaint of the battery dying overnight. The owner had already replaced the battery and alternator. We performed a parasitic draw test and found a significant draw coming from the interior lighting circuit. Even with all the doors closed and the truck off for 30 minutes, the BCM was keeping the retained accessory power (RAP) relay energized. It was a classic internal BCM failure. Swapping in a VIN-programmed 1999-2000 GM BCM like this one solved the draw instantly. It’s often these subtle, internal faults that cause the biggest headaches for owners.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all modules to power down completely.
- ✔ Locate the BCM: On most of these models, the BCM is located in the dash. For S10/Blazer platforms, it’s often in the center dash area. For Silverado/Sierra trucks and Astro/Safari vans, it’s typically on the driver’s side (LH dash).
- ✔ Remove Trim Panels: Carefully remove any lower dash panels or trim necessary to gain clear access to the module. Keep track of all screws and clips.
- ✔ Unplug and Unbolt: Disconnect all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Then, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and secure it. Reconnect all electrical connectors firmly until they click into place.
- ✔ Final Steps: Re-install the dash panels and trim. Reconnect the negative battery terminal. Your installation is complete.
