Restore Full Functionality to Your GM Vehicle

Are you battling bizarre electrical issues in your 2008-2012 Express 2500 Van? Flickering dash lights, malfunctioning power windows and locks, or an intermittent no-start condition can be incredibly frustrating.

The BCM is the central command center for your vehicle’s body electronics, and when it falters, it can create a cascade of problems. This replacement BCM, part number 20864768, is the definitive solution to get your workhorse van or family vehicle operating reliably again.

• ✔ Power windows, mirrors, or door locks operating erratically or not at all.
• ✔ Interior dome lights or dashboard lights staying on or not working.
• ✔ The security system preventing the vehicle from starting (blinking security light).
• ✔ The horn sounding unexpectedly or the panic alarm going off randomly.
• ✔ Inconsistent or non-functional heating and A/C controls.
• ✔ Communication error codes stored, such as U0140, U0155, or other U-codes.
• ✔ False warnings appearing on the driver information center.

A Straightforward Guide to Installation

Installing your cloned 2008-2012 Express 2500 BCM is a manageable job for a confident DIYer or any professional technician. The location can vary, but it’s often found in the center dash area on Express/Savana vans.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. Locate the BCM: On most Express and Savana vans, you will need to access the area behind the center dash or glove box to find the original BCM.
3. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
4. Install the New Module: Mount the new, cloned BCM in the same location and securely re-attach the electrical connectors you just removed. Ensure they click into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair was successful.
