I’ve been having a strange issue where my blind spot monitoring, passenger window controls, and center climate control panel panel will not come on. The lights on the center console flash for a second when the car starts and previously the whole system would work normally for a time if I unplugged battery and BCM fuses and reconnected them after some time. It seems my body control module has gone bad but I cannot locate the part number or even location of the module when searching online. I would appreciate any guidance on this.

Yep, it does sound like the BCM is is going out and is good for a while once rebooted which is common. But I would do a CAN scan to help confirm the issue, this video will show you how

Here is the location of the BCM in case you need to swap it out, Also I would use these guys for the rebuilt BCM.

The location of the BCM is under the dash on the drivers side. Check out the images (below). Let us know how it goes
