I’ve recently purchased an 07 Tahoe with a multitude of problems. But the one I’m currently trying to hunt down is a parasitic draw. It’s drawing about 200 mA. I’ve narrowed it down to the MBEC1 60A fuse, but when I tried to pull the circuit breakers in the box by the brake pedal. The 200 mA draw remains.

Looking at the wiring diagram it appears the MBEC1 only controls those three things by the circuit breakers. I believe it’s the passenger door and the two front seats. What am I missing?
