Replace BCM on 2001 Blazer
#6
BCM = Body Control Module. Depending on the year of the vehicle, among other items, it controls power door locks, power windows, all interior and exterior lights, (except instrument warning lights) horn, Passlock security system, retained accessory power circuit, and certain transfer case functions. All of which can be commanded seperately from a capable scan tool. When the operator selects a function on any of the various switches in the vehicle, a request is sent to the BCM. The BCM sends the command to the component.

Thank you for the information. Could a bad BCM be the problem with my 1998 Blazer LT 4WD? The power window switches work but none of the power lock or mirror switches work. Also, the back hatch window buttons don't work, neither the dash nor keyless remote.
If I want/need to open anything other than the driver door, I have to either reach over/back or use the remote, even when sitting in the vehicle.
