Default Power seat rear defog circuit dead short!?

I'm looking for likely places of a wiring short to ground in the power seat/rear defog circuit. There is a circuit breaker in the dash fuse panel for this circuit which as of now is hot on one side, and grounded on the other. The problem worsened over a few days. All was good, then battery was draining overnight, Checked amp load at battery, which was ~0.4A, then intermittently when battery was connected had HIGH current at battery terminal, a dead short.
With connections at seat and defog switch unplugged the circuit is testing as being grounded (and continuity between terminals) it has to have a wire pinched or somehow grounded from fuse box to seat or rear defog switch plugs.
The PO said he had the seats out (didn't say why, maybe this problem isn't new)
At least I managed to get the seat in a usable position (all the way back for me) before it fried out the circuit breaker in the fuse panel.
I have a schematic for the seat circuit, but info on the actual routing of the wiring would be a help too.

id start by taking the seat out and checking things out. allot of the things on these cars are ground switched so keep that in mind.

Got the seat out by taking it off he tracks. Found that the hot wire was smashed between the floor and seat mount. Just taped it up and It's good to go.
I suppose the PO had the seat out to fix the loose track. Which is still a little loose
