Only problem is getting at the fan in order to apply 12V; so your choice is between taking the car apart to test the fan, or plugging in the Durametric system and clicking on an icon. I know exactly where I would fall if faced with that choice.

We're certainly on the same page! So, is jumping at the relay also not a viable solution?

Doing that only test part of the harness and system, testing via the OBD II port tests everything.
