jinmcc, thanks for taking a look. I'm using Bentley manual wiring diagrams. The '86 looks very similar. The part I seem to be chasing is called the "blower control unit" on the wiring diagrams and it is physically located in the engine compartment on the left side. It is a twelve pin unit sitting next to what I think is the rear window defroster relay.

I took the cover off of the old unit and there are two relays inside with a bunch of other components. With the unit plugged into its connector, I can manually close the contacts of the larger relay looking thing and the engine compartment fan will run. What ever is controlling that relay seems to be the culprit.
