Default 2004 Silverado LBEC

Does anyone know what wires run from the LBEC fuse in the engine bay fuse box to the associated accessories? I'm trying to chase down a short, and I'm pretty certain my problem is between that fuse and the circuit breaker in the instrument panel fuse box.

the lbec 1 50amp fuse located in the ubec runs to the left ip fuse block located in the left side of the instrument panel.
the fuse feeds
-25 amp flasher fuse
-25 amp lt door circuit breaker
-15 amp tbc 2a
-15amp tbc 2b
-15amp tbc 2c

so you remove the cb and the fuse does not blow?

Yep, but even with everything after the CB unplugged, if I put the CB back in it still blows the fuse.

What all have you unplugged?

the fault is after the cb and before the window switch(crew cab) or driver door module. inspect the wiring that passes through the a-pillar into the door.

if the fault was between the fuse and cb...it would blow with the cb removed.
