Last project for a while... DEFROSTER

Last nonfunctioning piece of equip. I tested the voltage at the switch, the switch continuity, and continuity of the grid in the window. All seem okay.

The little light on the switch doesn't come on when I attempt to turn on the defroster. The grid doesn't heat up either. Got to be the wiring or a relay...

There's a relay somewhere right?? My FSM doesn't really say where though. I hate to remove, yet again, the plastic trim on the hatch but I suspect it's there?

Any thoughts?

No takers?
