<#2 Pulled wires off condensor behind driver's hedlamp assembly - No low Aux fan. Fuse on 15A relay is ok.

Re-read the test #2.
You do not disconnect that sensor..you jumper it at the pigtail wires for low fan.

It looks like he brought down power from F15 blower to work aux fan , but you want to do the test first so I know where you are....
