Cadillac Escalade body control module replacement due to suspected failure on Cadillac Escalade

Some Cadillac Escalade owners report experiencing issues related to the body control module (BCM), including problems with lights, power windows, door locks, and other electrical functions. These symptoms may indicate a BCM failure, making it essential to scan for error codes and check for any broken wires in the harness. Replacing the BCM requires removing the front floor console, disconnecting electrical connectors, and installing the new module along with components like the audio amplifier. Additionally, programming the new BCM often necessitates dealer involvement, as they possess the required tools and software. Owners are also advised to verify that the reserve accessory power (RAP) is functioning correctly before proceeding with the BCM replacement. Seeking professional assistance for programming is recommended to ensure the BCM operates properly.
