Default Draining Battery and TBC?
Does anyone have a circuit diagram of the TBC? My battery is draining and I have tracked it back to the TBC fuse [250mA+] constant drain. Not sure where to go from here.

2000 Blazer...

Thanks

I can tell you TBC fuse is one of the power inputs for the BCM and also powers your remote door lock receiver and multifunction switch (flash to pass) if that's any help. The first two of the three will be constant draws.
