Often it is the connection between the power supply wire and the grid in glass. That's what happened to my Toyota anyway, all seemed fine, light for defroster on but no heat/defrost

You were right about the power supply wire. At the Right, Front passenger door disconnect and fuse panel, a connector was 'smoked'. Only the contacts for the defogger wire were damaged. Pulled those wires out and bypassed the connector. All the rest of the wire I left in the connector. All is working well. Thanks to GM for another ''well thought out" job of engineering :(
