Jumpering the connector at the coolant temperature switch resulted in a healthy flow of air. While swapping in the 100/110C switch, I cracked up the connector pretty well

It is still very functional, but now on my junkyard list (since I'm OCD about having broken things on my stuff...

Still no aux fan operation with A/C on. Maybe the switch is not getting up to a high enough pressure to cause it to close, as I'm running envirosafe, which apparently operates at lower pressures. Maybe when the weather gets hotter it will start kicking on. (doubtful, but hey)
