Tired of Your Truck’s Electrical Gremlins?
Is your 2001 Sierra, Silverado, or Tahoe acting possessed? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or strange messages on the dash are all classic signs of a failing Body Control Module (BCM). These issues are more than just an annoyance; they compromise your truck’s functionality and reliability. This pre-programmed 2001 Sierra 1500 Body Control Module is the definitive solution to restore order and get your hard-working truck back to 100%.

If you’re experiencing any of the following, a faulty BCM is the most likely culprit. This module is designed to fix:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior or exterior lights staying on, flickering, or not turning on.
- The security or anti-theft system preventing the truck from starting.
- Erratic gauge cluster behavior or warning lights that won’t turn off.
- Communication error codes (U-codes) when scanned with a diagnostic tool.

They replace switches, check grounds, and test relays, only to find the BCM was the culprit all along. Buying a used module from a salvage yard is a gamble—it might have the same faults as your old one and will still require costly programming to work with your truck’s specific options. This VIN-programmed 2001 Sierra 1500 Body Control Module eliminates the guesswork and the extra expense, making it the smartest fix for any DIYer or professional shop.
Frequently Asked Questions
Do I need to program this module?
No. We handle all the programming for you. After you place your order, simply provide us with your vehicle’s VIN, and we will flash the module with the correct software before it ships. It will be ready to install right out of the box.
What exactly does a Body Control Module do?
The BCM acts as the central computer for your truck’s body electronics. It controls non-engine-related functions like power windows, door locks, interior and exterior lighting, the alarm system, and the instrument cluster. When it fails, it can cause a wide range of strange electrical issues.
What information do you need from me?
All we need is your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to program the BCM with the exact software and settings for your truck’s specific features and options.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a qualified technician with a professional-grade scan tool. This is only necessary if the airbag warning light is illuminated after the install.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your original module without any extra fees or the hassle of sending it back.
Will this fit my 2001 Silverado or Tahoe?
Yes. This 2001 Sierra 1500 Body Control Module is also the correct part for a wide range of 2001 GM trucks and SUVs, including the Silverado, Tahoe, Suburban, Yukon, and heavy-duty models. Please check the fitment list to confirm it matches your specific vehicle and options.
