Great idea!
I took a look at the '86 schematic, and on page 5 coordinates c22 you see a green/grey wire going to H2, and a green wire going to G1, both connected to B1 on the HVAC control unit through a 6 pin heating control connector. Unfortunately, the schematic is in error, as there is no connection going to coordinates G1, and this is where the power is coming from. However, the connection to coordinate H2 is power continuing on to the defroster switch light, and the ashtray light. If your ashtray light is working, then the connection through the 6 pin connector, or the connector to the HVAC control unit, or the wires in between, are suspect.
I just took another look, and I have to take back that the schematic is in error. The one I thought was in H2 is actually in G1 under where it says 'defroster switch light' and the H2 is left of 'front fog lamps.'
