Experiencing Strange Electrical Problems in Your GM Truck or Van?
If your Chevrolet Express 2500, Silverado, or Tahoe is suffering from baffling electrical issues like flickering lights, unresponsive power windows, or a dead HVAC system, a failing Body Control Module (BCM) is the most likely culprit. This central computer governs your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. Instead of spending hours on diagnostics or paying for expensive dealership programming, get the definitive, plug-and-play solution with our Programmed 15116066 Body Control Module.
Common Symptoms & Your Solution
A faulty BCM can make your reliable workhorse feel possessed. This module is the direct solution if you’re experiencing any of the following:
- Intermittent or completely dead HVAC controls and blower motor function.
- Power windows, door locks, or interior/exterior lights that work sporadically or not at all.
- An airbag warning light that won’t turn off, often accompanied by DTC B1001.
- Security system malfunctions that lead to a no-start condition.
- A variety of diagnostic trouble codes (DTCs) related to body electronics that seem to have no other cause.
Installing our pre-programmed BCM restores full, stable functionality to these critical systems, getting your vehicle back on the road and working as it should.

Expert Insight: The End of Diagnostic Headaches
As a technician, I’ve seen mechanics waste countless hours chasing what they think are bad grounds or faulty switches, only to discover the BCM was the real problem all along. These modules can fail internally, causing erratic signals that mimic other component failures. A vehicle might come in with a blower motor that only works on high, or power locks that have a mind of their own. The real fix isn’t a new switch or motorโit’s a properly functioning, correctly Programmed 15116066 Body Control Module. This part doesn’t just replace a component; it restores the vehicle’s electronic stability and saves you from the frustration of a comeback.
Frequently Asked Questions
Will this BCM really work without dealer programming?
Yes, absolutely. We program the module to your vehicle’s unique VIN before shipping it to you. This ensures it communicates correctly with your vehicle’s other systems right out of the box, making it a true plug-and-play installation.
Where is the BCM located on my vehicle?
On most compatible models like the Silverado, Sierra, and Tahoe, the BCM is located under the steering column on the driver’s side. On Express and Savana vans, it’s typically found behind the center dash panel. Installation usually takes just a few minutes.
My airbag light is on. Will this fix it?
This module can resolve BCM-related airbag codes like B1001. However, if the light remains on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may need to be performed with a professional scan tool to sync the new BCM with the airbag system.
Is this compatible with my 2005 Chevrolet Express 2500?
Yes, this Body Control Module is a confirmed fit for the 2004-2007 Chevrolet Express 2500 van, as well as a wide range of other GM trucks and SUVs. It is a direct replacement for part number 15137395 and others listed in the compatibility chart.
Do I need to return my old BCM?
No. We do not require you to return your original module. There is no core charge, which simplifies the process and saves you the hassle and cost of return shipping.
